Gonzalo Oliveira (born 17 February 1995 as Gonçalo Oliveira) is a former Portuguese-born Venezuelan tennis player who competed on the ATP Challenger Tour. He has a career high ATP singles ranking of world No. 194 achieved on 25 December 2017. He also has a career high doubles ranking of No. 77 achieved on 24 August 2020.
History
On 18 March 2019, Olivera reached the top 100 in the doubles rankings at world No. 99, the seventh Portuguese player to accomplish the feat.
In November 2024, he captured his maiden ATP Challenger Tour singles title at the inaugural edition of the 2024 Brazzaville Challenger, becoming the first player representing Venezuela to win a Challenger title in 24 years, since Jimy Szymanski in Tulsa in 2000. A month later, he reached his second Challenger singles final at the 2024 Manzanillo Open, where he lost to Mats Rosenkranz.
Following a provisional suspension, in October 2025 Oliveira was issued with a four-year ban by the International Tennis Integrity Agency (ITIA) backdated to January 2025 for an anti-doping rule violation after testing positive for methamphetamine. The test was taken at an ATP Challenger event in Manzanillo, Mexico in November 2024. His results from 25 November 2024 onwards were disqualified.
