The Heart Mountain War Relocation Center was a relocation camp located in northwestern Wyoming, United States, on an isolated site between the towns of Powell and Cody. The camp was used to imprison Japanese Americans during much of America's involvement in World War II.

Construction on the camp began in June 1942, and the first prisoners arrived in August. By October, about ten thousand people lived at the camp, making it the third-largest settlement in Wyoming. Most residents had been moved by train from California. The camp closed in November 1945.
