The Union of Democratic Forces-New Era (Union des Forces Démocratiques-Ère Nouvelle) was a political party in Mauritania, founded in 1991, and banned and dissolved in 2000.

In February 1997 the five-party Front of Opposition Parties (FPO), including the UFD-EN, was formed;[1] it boycotted the December 1997 presidential election, in which President Maaouya Ould Sid'Ahmed Taya was easily re-elected.

The UFD-EN under Daddah's leadership boycotted the January 1999 local election, in which the faction under Ould Maouloud participated.

[3] In October 2000, the UFD-EN was dissolved by the Government, which alleged that it incited violence and harmed national interests.

A successor party, the Rally of Democratic Forces (RFD), was subsequently established, with Daddah as its president.
