The Midwest Oil Company Hotel, at 136 East 6th Street in Casper, Wyoming, is an historic hotel building which was listed on the National Register of Historic Places in 1983. It has also served as the Casper Women's Club House. Originally built by the Midwest Oil Company to accommodate workers during the Casper oil boom, it was taken over by Standard Oil Company of Indiana when that company bought Midwest Oil. In the 1930s, in the waning days of oil production in Natrona County, a local women's organization bought the hotel for $8,000 and was renamed the Casper Women's Club House.
