The Port of Muskogee Railroad (reporting marks PMKX, PMR), formerly known as the Muskogee City-County Port Railroad (reporting mark MCCP), is a shortline railroad that operates at the Port of Muskogee in Muskogee, Oklahoma. The railroad began its operations on January 22, 1971, transporting freight between the industries at the Port of Muskogee, and from the Port of Muskogee to the Union Pacific and Burlington Northern & Santa Fe railroad lines. In the 1990s, Johnston's Terminal—one of the industries the railroad served—had owned several of their own locomotives until the Port of Muskogee bought their own locomotives.
