Maximiliano "Maxi" Nicolás Urruti Mussa (born 22 February 1991) is an Argentine footballer who plays for Montreal Impact in Major League Soccer.
Urruti started his career in the youth system at Newell's Old Boys in Rosario, Argentina until he was transferred to the senior squad in 2011. Urruti did not see consistent first-team action for the club, particularly after the return of Ignacio Scocco. In late 2012 and early 2013, several clubs including: Palermo, Levante, Valencia, Helsingborgs IF, and Toronto expressed interest in the player. He was officially signed by Toronto FC on 16 August 2013. He made his debut for the club the next day in a 2–0 away defeat to Columbus Crew, when he was a second-half substitute for Robert Earnshaw.
On 9 September 2013, Urruti was traded to Portland Timbers for Bright Dike, a first-round 2015 MLS SuperDraft pick, and an international roster spot for the remainder of the 2013 season.
