The Haddenham Cabin, located in Fossil Butte National Monument near Kemmerer, Wyoming, is a historic cabin that is listed on the National Register of Historic Places (NRHP).
It is an A-frame cabin that was designed and built c. 1918 by David C. Haddenham. It is notable for association with fossil quarrying in the Green River Formation; from seasonal work at this site Haddenham provided specimens of rare fossils to universities, museums, and private collectors. Located on the Quarry Trail, a 2.5 mile trail to Fossil Butte, once the center of a prehistoric lake; the cabin is about 2000 feet east of the fossil quarry.
It was listed on the NRHP in 2003. A photo accompanying its NRHP nomination shows an adjacent historic marker describing it as a fossil hunter's home.
