Chao Phraya Bodindecha (Thai: เจ้าพระยาบดินทรเดชา, personal name Sing Sinhaseni, สิงห์ สิงหเสนี 1777–1849) was one of the most prominent political and military figures of the early Bangkok Rattanakosin Kingdom. Bodindecha was both a top military general (แม่ทัพใหญ่) and Chief Minister in charge of civilian affairs as the Akkhra Maha Senabodi (อัครมหาเสนาบดี) of the Samuha Nayok สมุหนายก) during the reign of King Rama III. He was known for putting down the Laotian Rebellion (1826–1828} (ปราบกบฎ) of Lord Anouvong of Vientiane (เจ้าอนุวงศ์ เวียงจันทน์) and for campaigns during the Siamese-Vietnamese Wars of 1831–1834 and 1841–1845.
Sing was born in 1777 in Bangkok during the Thonburi Kingdom period to Chao Phraya Abhayraja (Pin) and Lady Fug. Abhayraja sent Sing under service to Prince Isarasundhorn, the heir apparent. The prince was later crowned as Buddha Loetla Nabhalai and Sing was made a minor official, during which time he became acquainted with Prince Chetsadabodin. Prince Chetsadabodin was crowned as Rama III in 1824 and Sing was made Phraya Ratchasuphawadi.
In 1826, Anouvong the King of Vientiane led the Laotian Rebellion against the Bangkok government. King Rama III sent his uncle (and titular heir-apparent) Maha Sakdi Polsep to Isan, accompanied by Sing (as Phraya Ratchasuphawadi) to suppress the rebellion (ปราบกบฎ, literally, "adjust" rebel.) The campaign earned Sing royal favor and he was elevated from Phraya to Chao Phraya Ratchasuphawadi and made Chief Minister in charge of civilian affairs. Rama III later granted Sing the special title Bodindecha (บดินทรเดชา) made up from parts of the king's own princely title, Chetsadabodin (เจษฏาบดินทร์).
