Hi-Yu is a non-profit organization, established in 1934 by West Seattle's service clubs to produce a summer festival to promote the West Seattle Community.

The annual Hi-Yu Summer Festival is held throughout the month of July. Dozens of events occur all around West Seattle during this time. The kick-off event is the Seattle Seafair Pirates Landing at Alki Beach, and it finishes at the end of the month with the Miss West Seattle Hi-Yu Scholarship Program and the Seafair Torchlight Parade.

Named in 1934 (16 years prior to Seafair), in a community contest, Hi-Yu means "much, plenty, abundance" in native Chinook jargon.
