Madison Park is an 8.3 acre (34,000 m2) park in the Madison Park neighborhood of Seattle, Washington, located between the western shore of Lake Washington on the east, 42nd Avenue E. on the west, E. Madison Street on the north, and E. Blaine Street on the south.

43rd Avenue E. divides it into two sections; the east is a swimming beach and public dock, and the west is a playground, playfield, and tennis courts.

Next to the beach is Madison Park Co-op, a community playhouse for toddlers and children.

(The construction of the Lacey V. Murrow Memorial Bridge in 1940 had greatly reduced demand and the continued existence of the run could no longer be justified after tolls were removed in 1949.)

From about 1890 to 1910 Madison Park was also a landing for steamboats which ran on Lake Washington.
