Kostas Mountakis (Κώστας Μουντάκης) (born 10 February 1926, Alfa in Mylopotamos, Rethymno Prefecture) is a Greek musician who popularized the traditional music of the island of Crete, primarily with the Cretan lira. His parents came from the village Kallikratis in Sfakia, Crete. His older brother Nikistratos was playing the lira and so did Mitsos Kafatos - one of the best musicians in Rethymno at that time - who was to become Kostas’ tutor.
When the German military occupation of Crete started, Kostas Mountakis was 15 years old. In those days, he played his lira and sang at the village coffee shop, and later at wedding receptions.
In 1952, Kostas Mountakis participated for the first time in an album recording when he accompanied Stelios Koutsourelis at the song “Arpaxsa kai Baildisa”. In 1954, he recorded his first personal album accompanied by the Koutsourelis brothers with the all time classics “De thelo stin kardia”, “O pramateutos”, “O argaleios”, “Milonades kai mazoxtres”, “Sto stadio pou m’efere”, “Rethemniane mou kantife”, “Harami sou”, Erotokritos”, “Kritikos Gamos”, “H mahi tis Kritis”, “O thanatos tou lirari”. These songs are a small sample of his music.
Kostas Mountakis played an important and vital role to the popularization of the lira as well as to the formation of its teaching methods. His overall contribution to the musical tradition of Crete is very important.
