Mazreku

Mazreku (archaic forms: Masarecu, Masareccu, Meserechus, Mânzaraku, Mazaraki or Mazarek) is an Albanian tribe or fis from the Dukagjin highlands. Historically they were one of the most widespread tribes, and placenames related to them are found throughout Albania: examples include Mazrek of Shkodër, Mazrek in Tiranë, Mazrek in Prizren and Mazarać in Vladičin Han.

The name Mazrek(u), which means "horse breeder" in Albanian, is found throughout all Albanian regions. Furthermore, the name relates to the Albanian word mëz - maz ('foal'), deriving from the Proto-Albanian *mandja and cognates to the Messapic word *menza ('foal').

Another Albanian tribe called the Mazreku lived in Epirus during the Middle Ages.
