Darius Dumitru Olaru (; born 3 March 1998) is a Romanian professional footballer who plays as a midfielder for Liga I club FCSB, which he captains, and the Romania national team. After starting out at hometown side Gaz Metan Mediaș and amassing over 100 appearances in the Romanian top flight, Olaru transferred to FCSB in 2020. Internationally, he represented Romania under-21 in two editions of the UEFA European Championship, in 2019 and 2021. Olaru went on to register his full debut for the country in June 2021, in a 1–2 loss to Georgia. Club career Gaz Metan Mediaș Olaru made his senior debut for Gaz Metan Mediaș on 29 August 2015, appearing in a 2–1 away win over UTA Arad in the second division.
