Troy is a town in Obion County, Tennessee, United States. The population was 1,423 at the 2020 census. It is part of the Union City, TN–KY Micropolitan Statistical Area.

Troy was founded in 1825 as the original county seat of Obion County. Frontiersman Davy Crockett was in attendance when the town was planted. The Paducah & Memphis Railroad extended its line from Union City to Trimble in May 1874. The line did not go through the town, but bypassed it to the south. In 1888, the Troy and Tiptonville Railroad started operations. This was a short line that connected the town with the (former Paducah & Memphis Railroad) Illinois Central Railroad at Moffat on the ICC line. Troy remained the county seat until 1890, when it was moved to Union City following a contentious legal dispute.

According to the United States Census Bureau, Troy has a total area of 1.4 square miles (3.6 km), all land.
