The cabinet of Thailand is a body composed of thirty-five of the most senior members of the government of the Kingdom of Thailand. The cabinet is the primary organ of the executive branch of the Thai government. Members of the cabinet are nominated by the prime minister and formally appointed by the King of Thailand. Most members are governmental department heads with the title of "minister of state". The cabinet is chaired by the Prime Minister of Thailand. The cabinet is often collectively called "the government" or "the Royal Thai Government".

The prime minister of Thailand is the head of government of Thailand. The prime minister is also the chair of the Cabinet of Thailand. The post has existed since the Revolution of 1932, when the country became a constitutional monarchy. Prior to the 2014 coup d'état, the prime minister was nominated by a vote in the Thai House of Representatives by a simple majority, and is then appointed and sworn in by the king of Thailand. The house's selection is usually based on the fact that either the prime minister is the leader of the largest political party in the lower house or the leader of the largest coalition of parties. In accordance with the 2017 Constitution, the Prime Minister can hold the office for no longer than eight years, consecutively or not. The post of Prime Minister is currently held by Pheu Thai Party politician and former CEO of Sansiri, Srettha Thavisin.
