Piłsudczyk (, pron. "Peewsudchyk") was a Polish armoured train of the early 20th century. It was among the first armoured trains serving the Polish Army and took part in the Polish-Ukrainian War of 1918-1919, the subsequent Polish-Soviet War and the Silesian Uprisings. Kept in reserve during the inter-war years, it was mobilised again in 1939 to be used during the Nazi-Soviet Invasion of Poland. "Piłsudczyk" was destroyed by its crew on 20 September 1939 at the train station at Mrozy.
