Ruangkrai Leekitwattana () is a Thai lawyer and political activist. A former senator and member of the Palang Pracharath Party, Ruangkrai has often sought the ouster of incumbent opposition candidates, including the current prime minister of Thailand Paetongtarn Shinawatra. His petitions often involve ethics complaints submitted to Thailand's National Anti-Corruption Commission.
In 2024, he sought to dissolve Thailand's progressive Move Forward Party due to the party's support of amendments to the lese-majeste law. The Constitutional Court dissolved the party in August 2024.
