2009–10 Liga I

Farul Constanța, Otopeni and Gloria Buzău were relegated at the end of the 2008–09 season. They were joined by Argeș Pitești, who were demoted upon a decision of the Professional Football League on 8 July 2009, after their owner, Cornel Penescu, was found guilty of corruption. As a consequence, 15th-placed Gaz Metan Mediaș were spared relegation. The four relegated teams were replaced by the champions and runners-up from both 2008–09 Liga II divisions. Ceahlăul Piatra Neamț and Ploiești were promoted from Seria I while Unirea Alba Iulia and Internațional Curtea de Argeș were promoted from Seria II. Promoted team FC Ploiești were renamed FC Astra Ploiești, effective to 1 July 2009. Venues Personnel and kits Managerial changes ==League table==
