Malin Sophie Diaz Pettersson (born 3 January 1994) is a former Swedish football midfielder who have played at club level for AIK, Tyresö FF, Eskilstuna United DFF, and Djurgårdens IF of the Damallsvenskan.

Malin was born to Swedish man Thomas Pettersson and Claudia Díaz, who had moved to Sweden from Chile aged eight after the 1973 coup d'état in her home country.

Tyresö had suffered a financial collapse in 2014 and withdrew from the league, expunging all their results and making all their players free agents.
