Maha Senanurak (Thai: สมเด็จพระบวรราชเจ้ามหาเสนานุรักษ์; 29 March 1773 – 16 July 1817) was a Viceroy appointed by his brother Phutthaloetla Naphalai as the titular heir to the throne.
Around the same time Prince Kasatranuchit, a son of King Taksin of Thonburi and his sister Princess Chimyai, staged a rebellion to reclaim the throne.
The rebellion was quickly suppressed by Prince Chetsadabodin (future King Rama III).
Maha Senanurak's wife, Princess Samlee, a daughter of Taksin, was executed for treason.
For the rest of his reign King Rama II refused to appoint a new Front Palace, perhaps leading to the brief confusion in the succession between his sons Chetsadabodin and Mongkut after his death in 1824.
