Colonel (RET) Gurcharan Singh Sekhon (Punjabi: ਗੁਰਚਰਨ ਸਿੰਘ ਸੇਖੋਂ, born 1937) is a retired Singaporean army officer.

[2] His early life was disrupted by the Japanese invasion and subsequently occupation of Singapore, and he described these experiences as formative.

Singh was reluctant, but did not want to disappoint his father, so he returned to Singapore in March 1966 and underwent recruitment tests.

Alongside Chng Teow Hua (who would later become Commissioner of the Singapore Civil Defence Force),[2] he was selected to attend a basic engineer officer's course in Fort Belvoir, Virginia.

He left for the course having just completed his training as an officer cadet, leaving him unable to attend his own commissioning ceremony.

[2] He was later selected to attend the United States Army Command and General Staff College at Fort Leavenworth, Kansas, from which he graduated in 1975.
