Wallingford is in north central Seattle, named after John Noble Wallingford. The QFC supermarket at the corner of N 45th Street and Wallingford Avenue N. may be regarded as the center of the neighborhood; its large W A L L I N G F O R D neon sign is made in part from letters in the old F O O D G I A N T sign that adorned QFC's predecessor for decades.

Wallingford's business district features many small shops, a few taverns and bars, the two Guild 45th movie theaters, the Wallingford Center (the former Interlake Elementary School, now turned into shops and apartments), and numerous restaurants including the original Dick's Drive-In, founded in 1954. Just north is Meridian Park, including the Good Shepherd Center, a former Roman Catholic home for wayward girls, now a community center with urban gardening plots.

Wallingford is home to Gas Works Park on Lake Union is just south of the Burke-Gilman Trail. To the northwest of Wallingford is Woodland Park, featuring the Woodland Park Zoo and a rose garden.

Annual events in the neighborhood include the Wallingford Wurst Festival and the What's Cookin' in Wallingford food festival, as well as the Family Fourth fireworks show every Independence Day at Gas Works Park.
