The World Kite Museum is a museum in Long Beach, Washington. First opened to the public on August 21, 1990, in a converted beach cottage acquired by the city. It opened with a collection of over 700 kites, exhibiting Japanese, Chinese, and Malaysian kites. It has grown to include galleries and exhibits on rotation with kites, models, and archives from around the world. The American Kitefliers Association combined their archives with the museum's in the late 1990s. The collection ranges from modern creations back to antiquity, and claims to have the most complete collection of Japanese kites outside of Japan. In 2005 the museum purchased a two-story building that currently houses over 1500 kites from 26 countries around the world.

The museum sponsors and hosts the Washington State International Kite Festival held annually in the city since 1981. The museum also sponsors the Windless Kite Festival, an indoor kite event held annually since 2001, and the One Sky One World International Kite Fly For Peace event held annually since 1985, in addition to other community events.
