Petroleum County is a county located in the State of Montana. As of the 2010 census, the population was 494, making it Montana's least populous county and one of the least populous counties in the United States. Its county seat is Winnett. The Montana Legislature approved the formation of the county by separating it from the Fergus County; Petroleum County was thus created on February 25, 1925, as the last of Montana's 56 counties to be created.
