Matías Nicolás Marín Vega

Matías Marín made his senior debut for Santiago Wanderers on 3 June 2018, having come through the club's youth academy, and by 2019 was part of the squad that won the Primera B title and returned Wanderers to the top flight. He was also on the books when the club lifted the Copa Chile in 2017, though he had yet to make competitive appearances for the first team at that point.

Marín left Wanderers in 2022 for O'Higgins before a move across the border in July 2023, when Belgrano de Córdoba brought him in for a fee reported at around €600,000–€680,000 for 80% of his rights. He spent 2025 back in Chilean football on loan at Unión Española, and in January 2026 joined Deportes La Serena on a further loan for the season, with ownership of his rights still held by Belgrano.

At youth level, Marín featured for Chile at the 2019 South American U-20 Championship, playing three matches, and was later called up to the national under-23 squad. He has not yet been capped by the senior side.
