Marco Trungelliti (Spanish pronunciation: ; born 31 January 1990) is an Argentine professional tennis player and competes mainly on the ATP Challenger Tour and ITF Futures, both in singles and doubles.
On 4 March 2019, Trungelliti reached his best singles rankings of world number 112. On 1 April 2013, he peaked at world number 174 in the doubles rankings.
At the 2018 French Open Trungelliti drove for 10 hours from Barcelona to Paris to be a late replacement for the injured Nick Kyrgios who had been due to face his compatriot Bernard Tomic. He only arrived to sign in shortly before midnight, and the match was scheduled first on court the following morning. Despite this Trungelliti defeated Tomic in 4 sets to make the second round at Roland Garros. He had been joined in his car journey by his mother and 89 year old grandmother who had happened to have been visiting from Argentina at the time. He lost to Marco Cecchinato in the second round.
