All 152 outdoor basketball courts in Seattle.

Green Lake Park is where Seattle basketball lives outdoors. The courts sit on the east side of the lake near the community center, and the park around them pulls 10,319 Google reviews at a 4.8 average, the biggest basketball-venue number in the city.

The history matters here. Green Lake's summer runs have been the proving ground for Seattle hoops across generations, the outdoor scene that fed a city which produced Jamal Crawford, Nate Robinson, Doug Christie, and Jason Terry. Ask any Seattle player of a certain age where the run was, and Green Lake is the answer.

The 2.8-mile loop path around the lake keeps thousands of people moving past the courts on any decent day, so the games always have an audience. Expect real competition on summer evenings and weekends, and a long wait for next if you show up alone at peak hours. Worth it.

Cal Anderson Park is Capitol Hill's front yard, 3,297 Google reviews at a 4.3 average, named for Washington's first openly gay state legislator. The basketball court sits at the Bobby Morris Playfield end of the park.

This is the most urban run in Seattle. The court sits minutes from the light rail station and the Pike/Pine nightlife blocks, so the crowd is whoever Capitol Hill is that evening: students, service workers off shift, tech workers, neighbourhood lifers.

The games are social first, competitive second, and the court rarely sits empty in daylight. Come for a casual run, stay because the park keeps the evening going around you.

Jefferson Park crowns Beacon Hill with 1,785 Google reviews at a 4.6 average, the best rating among Seattle's big park courts. The courts share the reservoir-lid park with a skatepark and lawns that look straight at the downtown skyline. The run draws Beacon Hill's international mix, and the level swings from family shoot-arounds to sharp weekend games.

Denny Park is Seattle's oldest park, set aside in 1884, and it now sits in the middle of the South Lake Union tech district with 1,711 Google reviews at a 4.2 average. The basketball court serves a lunchtime and after-work crowd that barely existed here fifteen years ago. Runs are quick, shirts-versus-badges affairs, strongest on weekdays when the offices empty out.

Judkins Park and Playfield stretches below the I-90 lid at the southern edge of the Central District, 723 Google reviews at a 4.4 average. Our OpenStreetMap check confirms two courts in the park. The run is neighbourhood-first, drawing from the CD and the north end of Beacon Hill, with summer evenings the reliable window.

Delridge Playfield anchors the Delridge corridor in West Seattle with 719 Google reviews at a 4.4 average, and Google lists basketball among its core facilities alongside the baseball fields and playground. The community center next door adds an indoor fallback when the rain arrives, which in Seattle is a feature worth ranking for.

Georgetown Playfield gives Seattle's most industrial neighbourhood its green heart, 579 Google reviews at a 4.3 average. Reviewers call out the basketball court alongside the covered picnic shelters and tennis courts. The run is small-neighbourhood friendly, and the surrounding Georgetown bar-and-arts strip makes the post-game options better than most parks can offer.

Hiawatha Playfield in West Seattle's Admiral district dates to the Olmsted Brothers' park plan and opened as one of the city's first purpose-built playfields more than a century ago. 518 Google reviews at a 4.5 average. The basketball court shares the grounds with a running track and ballfields, and the community center sits on site. The games are casual, the setting is classic Seattle parks.
