The Genuine Opposition (GO) was an electoral alliance in the Philippines that contested the 2007 Philippine general election. The alliance's members were in opposition to President Gloria Macapagal Arroyo. It was originally called the United Opposition (UNO), founded by Makati Mayor Jejomar Binay in June 2005 to unite all politicians who wanted to impeach President Arroyo. UNO then reorganized itself and changed its name to Grand and Broad Coalition (GBC), with the UNO party under that coalition. On February 15, 2007, the group changed its name again to Genuine Opposition after a meeting with Senate President Manny Villar due to the defection of senators Edgardo Angara, Tessie Aquino-Oreta, and Tito Sotto to Arroyo's senatorial slate, TEAM Unity.

In the Senate election, GO won seven of the 12 contested seats. They gained one more seat in 2011 after an electoral protest, through which GO's Koko Pimentel replaced TEAM Unity's Migz Zubiri.^[1] However, GO failed to dominate the House of Representatives.
