Martin Chrien born 8 September 1995) is a Slovak professional footballer who plays for Portuguese club Santa Clara, on loan from Benfica, as a midfielder.
Born in Banská Bystrica, Chrien made his professional debut for local club FK Dukla Banská Bystrica against MFK Košice on 1 December 2012. On 14 May 2014, he signed a four-year contract with Czech club Viktoria Plzeň, joining the senior team at the start of the 2014–15 season. He was then loaned to České Budějovice and Zbrojovka Brno in the Czech Republic, and Ružomberok in Slovakia, respectively.
On 29 June 2017, he moved to Portugal and signed a five-year contract with defending champions S.L. Benfica. He made his debut on 20 August 2017, in a league fixture against Belenenses, in a 5-0 win, coming on in the 71st minute of the match. Later in autumn he was moved to the B-team, playing number of games in LigaPro. During the winter transfer window he was initially linked with a loan to Croatian clubs Hajduk Split or NK Osijek, as he did not get sufficient play time at Benfica, but neither of the moves took place.
