The International Surfing Museum in Huntington Beach, California, is a nonprofit institution devoted to preserving surfing culture from around the world. Dedicated to Duke Kahanamoku, it presents surfing as both a sport and a wider cultural tradition through exhibits of historic surfboards, legendary surfers, classic surf films, sculptures, and surf music. Founded in 1987 by Ann Beasley and Natalie Kotsch, it moved from Walnut Street to 411 Olive Avenue in June 1990. Beasley and Kotsch were added in 1998 to the Honor Roll associated with the Surfing Walk of Fame, and in March 2026 the city council approved moving the museum into extra space in the library building.
