Republican Party for Democracy and Renewal

The Republican Party for Democracy and Renewal (الحزب الجمهوري للديموقراطية والتجديد; Parti républicain pour la démocratie et le renouvellement, PRDR) is a political party in Mauritania. Formerly known as the Democratic and Social Republican Party, (Parti Républicain Démocratique et Social, PRDS) the party changed its identity and adjusted its political stance after the 2005 coup. Formerly very supportive of President Maaouya Ould Sid'Ahmed Taya and his pro-Israeli policy, after the August 2005 coup, the party denounced Taya's policies and the mid-2006 Israeli military campaign in Lebanon.

In the 2001 parliamentary elections, the party won 64 out of 81 seats.

Sidi Mohamed Ould Boubacar, one of the bloc's members, was nominated as Prime Minister a few days after the 2005 coup.

The now-PRDR won seven seats in the November–December 2006 parliamentary election and in the 21 January and 4 February 2007 Senate elections, three out of 56 seats.

, the PRDR is part of the Mithaq El Wihda coalition and is led by Sidi Mohamed Ould Mohamed Vall.
