MV Leinster was a passenger ferry operated across the Irish Sea between 1937 and 1966.

MV Leinster was a passenger ship built by Harland and Wolff for the British and Irish Steam Packet Company in 1937.

[2] Leinster and her sister MV Munster took up their intended service between Liverpool and Dublin in 1938.

They were the largest vessels in the Coast Lines fleet and were to prove too large for that route.

[4] Shortly after the outbreak of World War II, the B&I ships were removed from their normal routes.
