Yakima Valley Museum, History museum in Franklin Park, Yakima, US.

Yakima Valley Museum is a 65,000-square-foot history museum in Franklin Park, Yakima, with exhibits on the valley's natural history, American Indian culture, pioneer life, early city life and fruit industry. Its collection of horse-drawn vehicles ranges from stagecoach to hearse, and it holds petrified Miocene trees and a Neon Garden of vintage neon lights.

The museum was founded in 1952 to preserve artifacts and stories about how the Yakima community developed over time. Its collections document how economic and social changes reshaped the region and the lives of its residents.

The museum displays objects from Plateau tribes and tells the story of how local communities lived with their surroundings through artifacts and exhibits. Visitors can see the connections between people and the valley across different time periods.

The museum stands at 2105 Tieton Drive, and the collections can be consulted for research by appointment. The Children's Underground, a 2,500 sq ft learning centre, runs programmes for ages 5 to 15. The nearby H. M. Gilbert Homeplace at 2109 W. Yakima Ave, an 1898 late Victorian farmhouse, is operated by the museum as well.

The museum holds a reconstruction of the Washington, D.C. office of Supreme Court Justice William O. Douglas, who grew up in Yakima. The display places his desk and working surroundings from the capital inside the valley museum, linking a national legal career to the town of his youth.
