Admiral Sangad Chaloryu (Thai: สงัด ชลออยู่; RTGS: Sa-ngat Chaloyu; 4 March 1915 – 23 November 1980) was a Thai admiral and politician who served as head of the National Administrative Reform Council (NARC), a military junta that ruled Thailand from 1976 to 1980.

[citation needed] As commander of a naval flotilla in 1954, he helped French Marines and elite forces escape from Vietnam after Hanoi was overrun by the Vietminh.

Sangad became chairman of NARC, which appointed royal favorite Thanin Kraivichien as Prime Minister.

In October 1977, NARC staged a second coup (this time without the king's consent), and replaced Thanin with Kriangsak.

[9][10] Sangad died from a heart attack on 23 November 1980 at Klaeng District Hospital, Rayong Province, at age 65 years.
