The Huron Subdivision or Huron Sub is a railway line owned and operated by the Rapid City, Pierre and Eastern Railroad (RCPE), a subsidiary of Genesee & Wyoming. The line stretches for 136 miles (219 km) across southwestern Minnesota and southeastern South Dakota, forming the eastern end of the RCPE shortline network. Originally the line was a part of the Chicago and North Western Railway. From 1986 it was a part of Dakota, Minnesota and Eastern Railroad, which later became a subsidiary of Canadian Pacific Railway.

The line is dark territory, meaning that it is not signalled and not equipped with centralized traffic control or automatic block signalling systems. The line is dispatched via radio using track warrant control.

Huron Subdivision connects with Canadian Pacific Tracy Subdivision at Tracy, Minnesota, as well as Pierre Subdivision and Yale Spur Subdivision (a former Great Northern Railway line) at Huron, South Dakota.

RCPE trains may continue to Mankato using trackage rights to interchange with the Union Pacific Railroad.
