This article lists political parties in Romania. Romania has a democratic multi-party system with numerous political parties, in which a political party does not often have the chance of gaining parliamentary majority alone, and, thus, parties must work with each other to form coalition governments. The current system was established following the Romanian Revolution of 1989 and the adoption of a new constitution in 1991; prior to these events, Romania was a single-party state under the rulership of the Romanian Communist Party (PCR).
