Laţcu was the Voivode of Moldavia between circa 1365 and 1373. He was the son of Bogdan I. His name is a diminutive form of Vladislav (or Ladislau), often used in that period in Hungary. During his reign, Roman Catholicism was introduced in Moldavia. On March 9, 1371, the Archbishop of Kraków appointed a man called Andrei as Bishop of Siret. On September 3, 1371, Pope Gregory XI appointed a second Bishop over Milcov. When Laţcu died, he was interred in the Rădăuţi church alongside his father Bogdan I.
