The Social Democratic Pole of Romania (Romanian: Polul Democrat-Social din România, PDSR)[2][3] was an electoral alliance in Romania ruling from 2000 to 2003 in a coalition government.

In 2001, the PDSR and PSDR merged into the Social Democratic Party (PSD).

The two remaining parties dissolved the alliance in 2004, ahead of the local elections, in which they competed against each other.

The PUR even attacked the PSD heavily for its system of "local barons".

For the parliamentary election in November, they still managed to set up a new alliance, called National Union PSD+PUR to counter the center-right Justice and Truth Alliance (DA).
