The Gray Panthers, founded in 1972 and still active as of 2020, are a series of multi-generational local advocacy networks in the United States which confront ageism and many other social justice issues. During the early years of the 1970s and 1980s, the main issues of the Gray Panthers included forced retirement, ageist stereotypes, cuts to Medicare and Social Security, and world peace. Over the years, the group worked to addresses other threats and social injustices such as the wars in Iraq, racism, campaign reform, and LGBTQ rights.

The Seattle Gray Panthers was founded in 1976, with headquarters in the Green Lake neighborhood. At some point, the group moved in the Good Shepherd Center in Wallingford, where they continue to hold monthly meetings as of 2020.
