The House of Representatives (Thai: สภาผู้แทนราษฎร, RTGSSapha Phuthaen Ratsadon, pronounced [sā.pʰāː pʰûː.tʰɛ̄ːn râːt.sā.dɔ̄ːn]) is the lower house of the National Assembly of Thailand, the legislative branch of the Thai government. The system of government of Thailand is that of a constitutional monarchy and a parliamentary democracy. The system of the Thai legislative branch is modelled after the Westminster system. The House of Representatives has 500 members, of which 400 are elected through single member constituency elections, while the other 100 are chosen through party lists parallel voting.

The House of Representatives has been abolished several times as a result of military coups, most recently as a result of the 2014 Thai coup d'état, when it was replaced with the unicameral National Legislative Assembly, a body of 250 members, selected by the National Council for Peace and Order. After the 2017 constitution was promulgated in April 2017, the House of Representatives was reestablished.
