Vitas, O.P., or Wit (died c. 1269) was a Polish Dominican friar from the Kraków convent[1] and the first bishop in Lithuania (1253–1255).

Following the conversion to Christianity and coronation of King Mindaugas during the summer of 1253,[4] there was some delay in appointing a bishop for the Grand Duchy of Lithuania due to political intrigues.

[2] In 1254, the priest Christian (Lithuanian: Kristijonas), a member of the Livonian Order, was appointed bishop and recognised by King Mindaugas with the grant of lands in Samogitia.

[5] In 1254, Vitas wrote to Pope Innocent IV about the deplorable conditions of Christians in Lithuania and asked for a transfer.

[7] Historian Jan Kurczewski believes that Vitas established a Dominican church and monastery in the city of Lubcha, in present-day Belarus.
