Pennsylvania Railroad 1361 is a K4 class 4-6-2 "Pacific" type steam locomotive built in May 1918 by the Pennsylvania Railroad's (PRR) Juniata Shops in Altoona, Pennsylvania. It hauled mainline passenger trains in Pennsylvania and commuter trains in the northern New Jersey Shore on the PRR until its retirement from revenue service in 1956. Afterwards, in 1957, it was refurbished and put on static display next to the PRR's famous Horseshoe Curve in Blair County, Pennsylvania.

Restored to operating condition for excursion service in 1987, No. 1361 and its other surviving fellow K4 locomotive, No. 3750, were designated as the official state steam locomotives by the Pennsylvania General Assembly. In late 1988, it was sidelined due to mechanical problems and a second restoration attempt stalled. As of 2025, the locomotive is owned by the Railroaders Memorial Museum (RMM) in Altoona, Pennsylvania where is it has been undergoing operational restoration.
