The Țiriac Open (also known as the Romanian Open) is a professional men's tennis tournament played on outdoor clay courts. It was the successor event to the earlier Romanian International Championships (1930–1983). It is part of the ATP 250 tournaments of the ATP Tour. It was held annually in Bucharest, Romania, between 1993 and 2016 and revived in 2024. Its name is taken from Romania's famous tennis players Ion Țiriac and Ilie Năstase (when it was called BRD Năstase Țiriac Trophy until 2016).

The tournament never saw a Romanian winner in singles (though the 2005 edition saw two Romanian players reaching the semifinals, and the 2007 edition saw Victor Hănescu reach the finals), but a Romanian pair (Andrei Pavel and Gabriel Trifu) took home the doubles title in 1998. Also, Horia Tecău took three consecutive doubles titles at the tournament (2012, 2013 & 2014), each time with a different partner.

The organizers announced that from 2012, the ATP World Tour 250 series tournament would be scheduled to take place in April, thus ending a period of 19 years when it took place in the last week of September.

The last edition of the tournament was in 2016, as ATP has relocated it to Budapest. The tournament moved to Belgrade in 2021 and to Banja Luka in 2023. In 2024, the tournament returned to Bucharest.
