Chao Phraya Bodindecha (Thai: เจ้าพระยาบดินทรเดชา, Khmer: ចៅ ឃុន បឌិន,[1] 13 January 1776 – 24 June 1849), personal name Sing Sinhaseni (สิงห์ สิงหเสนี), was a prominent military figure of the early Rattanakosin Kingdom period during the reign of King Rama III.

Bodindecha was born on 13 January 1776 in modern Phra Nakhon District during the Thonburi Kingdom period, with personal name Sing (lit.

He joined his lord in the campaign against Burmese Invasion of Phuket in 1809 and rose through ranks in Front Palace Police Bureau.

When Prince Chetsadabodin was crowned as King Rama III in 1824, Bodindecha was made Phraya Ratchasuphawadi the Head of Krom Suratsawadi or Conscription Department.

King Rama III then elevated Bodindecha to Chaophraya Rajasupawadi and transferred the responsibilities of the Samuha Nayok to him.

When Prince Maha Sakdi Polsep, the leader of the campaign, returned to Bangkok, Bodindecha was left in charge in Laos.

During this time, Emperor Minh Mạng sent Vietnamese envoys to bring Anouvong from Nghệ An Province back to Vientiane to negotiate.

Bodindecha decided to meet his enemies at Bokwan (modern Si Chiang Mai District, Nong Khai Province).

Rattanakosin Chronicles of the Third Reign from 1931 gives accounts on personal engagements between Bodindecha and Raxavong Ngao in the Battle of Bokwan.

Upon his return to Bangkok, King Rama III officially invested him with the title of Chaophraya Bodindecha the Samuha Nayok Prime Minister of Northern Siam.

Bodindecha marched through Cambodia virtually unopposed as King Ang Chan had fled to southern Vietnam along with his court.

Bodindecha joined Phraklang at Châu Đốc, An Giang Province in 1834 and they both marched the fleet along the Bassac River to Saigon.

After repeated Vietnamese attacks on Châu Đốc, Bodindecha decided to retreat to Battambang, his main base.

One year after his return to Bangkok, on 24 June 1849, Bodindecha died during the Cholera epidemic, aged 73, at his residence near modern Sampheng, Samphanthawong District.
