Somdet Phra Boworaratchao Mahasurasinghanat (Thai: สมเด็จพระบวรราชเจ้ามหาสุรสิงหนาท; 1 November 1744 – 3 November 1803), born Bunma (Thai: บุญมา), was a Thai military leader and statesman who served as the first Front Palace of the Chakri Dynasty. As the younger brother of King Rama I, he was a foundational figure in the establishment of the Rattanakosin Kingdom and played a decisive role in securing Siam's independence from Burmese incursions during the late 18th century.
Rising to prominence during the Thonburi Kingdom under King Taksin, he held the title of Chao Phraya Surasi and became renowned for his fierce and tactical combat style, earning the moniker "Phraya Suea" (The Tiger Lord). Following the accession of Rama I in 1782, he was appointed the Viceroy and took up residence in the newly constructed Front Palace, where he oversaw the defense and administration of the northern provinces.
His military career is defined by several critical victories that ensured the survival of the nascent Chakri state. Most notably, he led the Siamese defense in the Nine Armies' War (1785), where his strategic maneuver at the Battle of Lat Ya effectively repelled a massive Burmese invasion. He further solidified Siamese dominance through the Tha Din Daeng campaign (1786), the capture of Tavoy (1787), and the liberation of Chiang Mai from Burmese control (1795–1802).
Beyond his martial achievements, Mahasurasinghanat was a patron of the arts and religion. He oversaw the restoration of numerous temples, including Wat Mahathat Yuwaratrangsarit, and authored several literary works that provide significant historical and emotional insight into the transitional period between the fall of Ayutthaya and the rise of Bangkok.
