The Blue Moon is a tavern located on the west edge of the University District, Seattle, Washington, that has been visited by many counterculture icons over the years. It opened in April 1934, soon after the repeal of Prohibition in December 1933. It is the first and oldest tavern in the U-District. It was an instant hit with students (together with the still-thriving Duchess Tavern in Ravenna); under state law, students had to trek one mile from the campus to purchase drinks. The Blue Moon was one of the rare bars outside of the Central District to serve African American servicemen during World War II. The tavern also provided a haven for UW professors such as Joe Butterworth who were caught up in the McCarthyist purge. It had further heyday in the 1950s and 1960s. Regulars included author Tom Robbins, poets Theodore Roethke, Richard Hugo, Carolyn Kizer, Stanley Kunitz, and David Wagoner, and painters Richard Gilkey and Leo Kenney.
