Martin Guarino (born 24 October 1990 in Buenos Aires) is an Argentine professional footballer who plays for Defensores de Belgrano as a left defender.
Guarino made his league debut for Dutch side FC Zwolle on August 7, 2009, in the away match against AGOVV Apeldoorn.
The game ended in a 2–0 defeat for Zwolle.
At the end of the 2009–10 season, Guarino and teammate Dennis van der Wal were told that they could leave if they found a new club.
Both players did not find a new club, so they stayed at the club for the 2010–11 season.
