Marcelo Arévalo González (Latin American Spanish: [maɾˈselo aˈɾeβalo ɣonˈsales]; born October 17, 1990) is a Salvadoran professional tennis player. He is the current world No. 1 in doubles by the ATP, achieved on 11 November 2024 and has a career-high singles ranking of No. 139 , attained in April 2018, making him the highest-ranked player, male or female, across both disciplines in Salvadoran tennis history.
He has won thirteen career ATP Tour doubles titles, including two Grand Slam titles at the Roland Garros in 2022 with partner Jean-Julien Rojer and in 2024 with Mate Pavić. With the win, he became the first player from Central America to claim a men's doubles major title. He had previously reached one other Grand Slam final, having lost at the 2021 US Open in the mixed doubles tournament with partner Giuliana Olmos.
As a junior, Arévalo was ranked as high as No. 8 in the world and won seven singles and doubles titles on the ITF Junior Circuit. As a professional, he broke into the top 100 in 2018 and won his first ATP title at the 2018 Los Cabos Open with Miguel Ángel Reyes-Varela, making his debut in the top 50. After several years with intermittent partners, Arévalo formed a new partnership with Rojer in 2022 that took them to four additional tour finals, three of which they won, and helped him debut in the top 10.
