Seward Park is a suburban neighborhood in south Seattle, Washington just west of the park of the same name. The park itself occupies all of Bailey Peninsula, a large, forested peninsula that juts into Lake Washington.

The neighborhood is bounded on the east by the lake, on the north by South Genesee Street, on the south by South Kenyon Street, and on the west by Rainier Avenue South.

Seward Park, which was first settled in the 1880s, is built on the largest residential hill in Seattle. Around a quarter of the residents are black, and another quarter Asian American, most of the remainder being white. The neighborhood has been a hub of Orthodox Jewish life for nearly 90 years. The oldest synagogue in Washington state, Bikur Cholim-Machzikay Hadath, is located there, as are Sephardic Bikur Holim Congregation and Congregation Ezra Bessaroth. 90% of Orthodox Jews in Seattle are said to live within a mile of one of the synagogues, though more recent arrivals have been settling north of the Lake Washington Ship Canal in Wedgwood, Hawthorne Hills , and Ravenna.

The quality and value of the houses tends to decline the further one goes from the lake toward Rainier Avenue; at the same time the crime rate goes up.

Seward Park is home to Whitworth and Graham Hill Elementary Schools.
