Largest Charities in Washington State: Top 10 Organizations to Donate & Volunteer (2026)

Northwest Harvest is Washington's only statewide food bank, distributing food through a network of more than 375 partner food banks, pantries, senior centers, and community programs across all 39 Washington counties. They hold a Feeding America membership and emphasize fresh produce and culturally appropriate foods — a priority in a state where the food-insecure population includes large Hispanic/Latino farmworker communities in eastern Washington, Indigenous communities across multiple tribal nations, and diverse immigrant populations in the Puget Sound region.

Northwest Harvest's 2026 key facts report was notable for specifically calling out that the current federal administration has declined to publish the annual USDA Household Food Insecurity Report going forward — a transparency loss that directly limits the organization's ability to accurately assess and report on food insecurity in Washington and nationwide. Their own data shows Washington food bank visits reached 13.3 million in fiscal year 2024. Northwest Harvest has multiple volunteer sites across western and eastern Washington. Their Eastern Washington region, centered on Yakima, sees particularly high food insecurity rates among the agricultural workforce.

Food Lifeline is the primary food bank for the western Washington counties surrounding Seattle, distributing food through a network of hunger relief agencies across King, Pierce, Snohomish, Skagit, and Whatcom Counties. As a Feeding America member, they source, store, and distribute donated and purchased food to partner food banks and pantries across the region. The Seattle metro's food insecurity story is counterintuitive to many outside the region: the most economically productive corner of Washington — with Amazon, Microsoft, Boeing, and the tech sector's supply chain — also has food bank visit rates that have tripled in three years.

Food Lifeline distributes food to 275+ hunger-relief organizations and programs across their service area. The food bank received support from multiple Seattle-area corporate partners during the November 2025 SNAP disruption and emergency food declaration. Volunteers sort and pack food at the Food Lifeline warehouse. Their scale makes them one of the most impactful volunteer opportunities in the Seattle area — individual shifts contribute to millions of meals annually.

The Humane Society for Seattle/King County is the primary humane society for the greater Seattle area, operating from a campus in Bellevue with programs including adoption, spay/neuter, humane education, wildlife rescue coordination, and community pet support. King County's rapid population growth and housing costs have created animal welfare challenges that track closely with human economic distress: when people lose housing, get evicted, or face economic crises, pets are often surrendered. The Humane Society's pet retention programs provide temporary pet boarding, emergency pet food, and other support to help owners keep their animals.

Washington's other significant animal welfare organizations include PAWS (Progressive Animal Welfare Society, Lynnwood), Seattle Animal Shelter (municipal), Pasado's Safe Haven (Monroe), and many county shelters. The Humane Society for Seattle/King County is the largest private humane organization in the state. Volunteer roles include animal care, dog walking, cat socialization, wildlife reception, and foster care. Given the Seattle area's tech workforce, the Humane Society receives significant corporate volunteer days from Amazon, Microsoft, and related companies.

Habitat for Humanity Seattle-King and Kittitas Counties builds affordable homes in the greater Seattle metro during a period when Seattle has become one of the least affordable housing markets in the United States. Median home prices in King County have exceeded $850,000; even renting a one-bedroom apartment in Seattle runs $2,400 or more per month. For Habitat families — those earning 30–80% of area median income — the gap between wages and housing costs is so extreme that without Habitat's sweat equity model and below-market mortgage, homeownership is genuinely out of reach regardless of financial behavior.

Habitat Washington has affiliates in Tacoma (Pierce County), Bellingham (Whatcom County), Spokane, Tri-Cities, and other communities. The Seattle affiliate's work is among the most visible given the scale of the region's housing crisis and the concentration of philanthropic resources. ReStore locations accept building materials and goods. Build days run year-round, open to first-timers. Corporate volunteer groups from Amazon, Microsoft, and Boeing regularly build with Habitat.

The Bill & Melinda Gates Foundation is headquartered in Seattle's South Lake Union neighborhood and operates with approximately $70 billion in endowment assets — the world's largest private charitable foundation. It distributes roughly $6–7 billion annually to global health, global development, US education, and Washington state programs. While most Gates Foundation giving is global or national, the Foundation has a specific Washington state program that funds K-12 education improvement, college access, and community development in the state where the Foundation is headquartered.

The Gates Foundation is not a conventional giving target — it doesn't accept donations from the public. It's included here because its presence in Seattle is fundamental to understanding the state's philanthropic landscape. The Foundation's grant decisions influence billions of dollars in nonprofit activity worldwide and its Seattle headquarters makes Washington one of the highest per-capita philanthropic capital states in the country. For Washington residents wanting to give through a community foundation rather than directly to nonprofits, the Seattle Foundation manages grants across King County causes.

United Way of King County manages workplace giving campaigns for major Seattle-area employers — Amazon, Microsoft, Boeing, Starbucks, Alaska Airlines — and distributes grants to nonprofits across King County. They operate 2-1-1 Washington, connecting residents to food, housing, utility, and emergency resources statewide. The Seattle tech sector's corporate giving culture is significant: Amazon alone runs one of the largest AmazonCares employee giving campaigns of any company in the country. United Way of King County's annual campaign benefits from this concentration of well-paid workers with active charitable giving habits.

Washington has multiple United Way chapters — United Way of Pierce County (Tacoma), United Way of Snohomish County (Everett), United Way of Spokane County, and others. King County's chapter is the largest by campaign volume. After the November 2025 SNAP disruption, 2-1-1 Washington call volume increased sharply. United Way of King County's Home Base program specifically targets family homelessness prevention in King County.

The Red Cross Pacific Northwest Region covers Washington, Oregon, and Alaska, responding to home fires, wildfires, earthquakes, flooding, winter storms, and volcanic activity. Washington's disaster profile is distinctive: the Cascadia Subduction Zone creates catastrophic earthquake and tsunami risk for the entire western portion of the state; the Cascades have active volcanoes (Mount Rainier's potential collapse is the subject of ongoing emergency planning); and western Washington wildfires have become more severe with drought and warming temperatures. Eastern Washington's agricultural communities face regular flooding from the Yakima and Columbia River systems.

Blood collection runs at donor centers statewide — Harborview, Swedish, Seattle Children's, and Providence are major consumers. Blood donation appointments are available within days at most Washington chapters. If you were displaced by a wildfire, earthquake, or other disaster in Washington and need immediate help, call 1-800-RED-CROSS.

Catholic Charities of Western Washington covers the Archdiocese of Seattle with refugee resettlement, immigration legal services, housing programs, emergency assistance, and counseling. Seattle is one of the primary refugee resettlement cities in the country — the Washington area has welcomed significant communities from Somalia, Ethiopia, Afghanistan, Ukraine, Burma, and other countries. Catholic Charities provides resettlement coordination and ongoing legal and social support for those families. Their immigration legal services program handles a large caseload given western Washington's significant immigrant population from Mexico, Central America, and Southeast Asia.

Catholic Charities also runs St. Vincent de Paul programs and housing support in partnership with King County. Catholic Charities of Eastern Washington covers the Spokane area separately. Services are available to people of all faiths. Volunteers assist with English tutoring, resettlement support, food assistance, and administrative roles.

The Salvation Army operates across Washington — Seattle, Tacoma, Spokane, Bellingham, Olympia, Yakima, and many other communities. Programs include emergency food, rent and utility assistance, overnight shelter, after-school programs, and disaster canteens. Seattle and King County's homelessness crisis is among the most visible in the country — the encampments, shelter capacity debates, and political battles over addressing homelessness in Seattle have been national news for years. The Salvation Army's downtown Seattle operations provide emergency shelter and food for one of the more visible urban homeless populations in the US.

Spokane's Salvation Army is among the most active in eastern Washington given Spokane's significant poverty and homelessness. Red Kettle campaign runs November through Christmas. Thrift stores accept goods year-round. Emergency assistance is available at local corps statewide — call before visiting to confirm current program availability.

Big Brothers Big Sisters of Puget Sound matches children facing adversity with adult mentors across King, Pierce, and Snohomish Counties. Washington's wealth concentration in the tech sector means some of the most significant income disparities in the country run through Seattle's neighborhoods — South Seattle, Rainier Valley, and White Center have child poverty rates well above the tech-corridor communities of Bellevue and Kirkland. BBBS research consistently shows matched youth are more likely to graduate, avoid the justice system, and find stable employment.

Community-based mentoring requires meeting 2–4 times per month for at least a year. School-based mentoring runs weekly. Washington state has BBBS affiliates in Spokane and other regions. The Puget Sound chapter benefits from the tech sector's volunteer culture — Amazon, Microsoft, and tech-adjacent employers run corporate mentoring initiatives that supplement the traditional BBBS model. Demand consistently exceeds available volunteers.
