Koalisyon ng Nagkakaisang Pilipino

The Koalisyon ng Nagkakaisang Pilipino (KNP) (Coalition of United Filipinos), also known as the United Opposition, was the political multi-party electoral alliance of the dominant opposition in the Philippines during the 2004 general elections. The KNP was composed of the Laban ng Demokratikong Pilipino (Fight of Democratic Filipinos) or LDP, the Partido Demokratiko Pilipino-Lakas ng Bayan or PDP–Laban, and the Pwersa ng Masang Pilipino (PMP) of deposed president Joseph Estrada, a former movie star.

The leading party of this coalition is the Angara wing of the Laban ng Demokratikong Pilipino (Struggle of Democratic Filipinos) or LDP. The LDP split in late 2003 over issues on who is to be their standard bearer. Most of the party followed the lead of the president, Sen. Edgardo Angara especially with the support of the former president Joseph Estrada and former first lady Imelda Marcos. The other major party under this coalition is Estrada's Pwersa ng Masang Pilipino (PMP; Party of the Philippine Masses).

The KNP chose Fernando Poe Jr. (died December 14, 2004) as their candidate for president and Sen. Loren Legarda for vice-president in the 2004 Philippines elections.

After the 2004 elections, the KNP was replaced by the Genuine Opposition as the main opposition coalition.
