The Lipka Tatars (also known as Lithuanian Tatars, Polish Tatars, Lipkowie, Lipcani or Muslimi, Belarusian Tatars) are a group of Tatars who originally settled in the Grand Duchy of Lithuania at the beginning of 14th century.

According to some estimates, by 1591 there were about 200,000 Lipka Tatars living in the Polish-Lithuanian Commonwealth and about 400 mosques serving them.

Today there are about 10,000-15,000 Lipka Tatars in the former areas of the Polish-Lithuanian Commonwealth. The majority of descendants of Tatar families in Poland can trace their descent from the nobles of the early Polish-Lithuanian Commonwealth.
