The Western Antique Aeroplane and Automobile Museum (WAAAM) is located in Hood River, Oregon, United States, adjacent to the Ken Jernstedt Memorial Airport.

WAAAM is a nonprofit 501(c)(3) organization committed to the preservation of, and education about aviation, automobile, and other historic transportation-related relics.

WAAAM is open to the public every day 9:00-5:00 except Thanksgiving, Christmas, and New Years.

The museum's biggest event is the annual Hood River Fly-In held the first weekend after Labor Day every year, and features antique aircraft and automobiles from throughout North America.

The museum was formed as a 501(c) organization in 2006, by collector Terry Brandt and opened in 2007, in a 95,000-square-foot (8,800 m2) building.
