The Sosa-Carrillo-Fremont House is a historic adobe house at 145-153 South Main Street in Tucson, Arizona, built in the 1870s as a remnant of the city's old barrio, now surrounded by the Tucson Convention Center. It is known locally for its association with John Charles Fremont, a former Territorial Governor of Arizona, and is also known as the Carrillo House, the Leopoldo Carrillo House and the Carrillo-Fremont House. Listed on the National Register of Historic Places in 1971 as the John Charles Fremont, Casa del Gobernador, House, its official name was later changed to better reflect its association with several families significant to the region's history. The house is owned by the Arizona Historical Society and operates as a museum.
