Thai Nation Party, or Chart Thai Party was a conservative political party in Thailand. It was dissolved by the Constitutional Court of Thailand on December 2, 2008, along with the People's Power Party and the Neutral Democratic Party, for having violated electoral laws in the 2007 Thai general election. Thereafter, most MPs founded the Chart Thai Pattana Party, which became the Thai Nation Party's successor.

The People's Power Party is a defunct Thai political party. The party leader was Somchai Wongsawat, the Party Secretary General was Surapong Suebwonglee, and the Party Spokesperson was Kuthep Saikrajarng. Most MPs of the party originally hailed from the Thai Rak Thai Party and thus the party was its de facto reincarnation with former prime minister Thaksin Shinawatra as its "leader." The PPP had a populist platform and was strong in the North, Central, and Northeastern regions of Thailand. The party became the leader of the coalition government after the junta-government supported 2007 general election. PAD, the leading anti-Thaksin movement, vowed to oppose it after the party decided to launch the amendment of the 2007 Constitution.
