The Western River Expedition (WRE) was a Disney theme park attraction that was designed but never built. It was to be a western themed boat ride, slated to appear in the northwestern section of Frontierland at the Magic Kingdom, a theme park at the Walt Disney World Resort in Lake Buena Vista, Florida, United States.

Frontierland is one of the "themed lands" at the many Disneyland-style parks run by Disney around the world. Themed to the American frontier of the 19th century, Frontierlands are home to cowboys and pioneers, saloons, red rock buttes and gold rushes along with some influence from American history and North America in general. It is named Westernland at Tokyo Disneyland and Grizzly Gulch at Hong Kong Disneyland.
