The International Pop Underground Convention was a 1991 punk and alternative rock music festival in Olympia, Washington. The six-day convention centered on a series of performances at the Capitol Theater. Throughout August 20–25, 1991, an exceptionally large number of independent bands played, mingled and collaborated at the Capitol and other venues within the Olympia music scene. A compilation of live music from the event was released later by the local record label K Records.

The port city of Olympia, Washington, has been a center of post-hardcore, anti-folk, and other youth-oriented musical genres since the late 1970s. Before this period, Olympia's The Fleetwoods had several Billboard chart successes between 1959 and 1963. Olympia saw a rise in feminism in the music industry, where artists commonly addressed rape, domestic abuse, sexuality, racism, patriarchy, classism, anarchism, and female empowerment in their songs. It was a center for the riot grrrl movement of the early 1990s, which featured Bikini Kill and Bratmobile.
