18th Pomeranian Uhlan Regiment (Polish: 18 Pulk Ulanów Pomorskich, 18 p.ul.) was a cavalry unit of the Polish Army in the Second Polish Republic. Formed in April 1919 in Poznań, it fought in the Polish-Soviet War and the Invasion of Poland. In the interbellum period, the regiment was garrisoned in Grudziadz (since September 1923). Pomeranian uhlans became famous for the legendary Charge at Krojanty, after which the unit ceased to exist.
