Apostol Mărgărit or Apostolos Margaritis (5 August 1832 in Avdella – 19 October 1903 in Bitola) was an Aromanian school teacher and writer. One of the most important voices of Aromanian emancipation in the 19th century, he conditioned Romania's policy toward the Aromanians, who started to have their own schools in their own language, thanks to Mărgărit's efforts.
