Gerónimo Rulli (Spanish pronunciation: [xeˈɾonimo ˈruli]; born 20 May 1992) is an Argentine footballer who plays as a goalkeeper for Ligue 1 club Marseille and the Argentina national team.

Born in La Plata, Buenos Aires Province, Rulli graduated from local Estudiantes' youth setup, being promoted to the first-team squad in 2012, being initially assigned as a backup to Justo Villar and Agustín Silva.

On 8 April 2013, after profiting from Villar's departure to Nacional and Silva's injury, he played his first match as a professional, starting in a 0–1 loss at Arsenal de Sarandí.

On 24 July 2014 Rulli was loaned to La Liga's Real Sociedad for one year from Deportivo Maldonado,[4] which bought the player's rights a month earlier.

[5] He made his debut for the club on 28 August, starting and being replaced in the 85th minute of a 0–3 away loss against Krasnodar in the 2014–15 UEFA Europa League due to an ankle injury.

[6] Rulli returned to action in November, and made his debut in the main category of Spanish football on 20 December 2014, starting in a 1–1 away draw against Levante.

In the second half, he made goalkeeping errors and conceded three goals, in which his team eventually lost 3–2 in the Estadio de la Cerámica, and was knocked out of the competition.

[28][29] On 1 June 2022, Rulli remained as an unused substitute as Argentina won 3–0 against reigning European Champions Italy at Wembley Stadium in the 2022 Finalissima.

He did not play a single minute in the tournament as Argentina won the World Cup by defeating France 4–2 in a penalty shoot-out to win the final.
