Grantley Thomas Smart Goulding (born 23 March 1874 in Hartpury, Gloucestershire, England; died 29 July 1947 in Umkomaas, KwaZulu-Natal, Union of South Africa) was a British athlete.

Goulding first gained prominence as a local athlete in the Gloucestershire area when he won a number of races in the 1895 season.

In a meeting at Gloucester he defeated the visiting South African champion but was less successful at the AAA championships where he finished last in his heat.

A stumble from Goulding at the start of the race appears to have been decisive; although he gained ground on Curtis after halfway, he could not close the gap.

In 1932, Curtis wrote in The Sportsman that Goulding "stopped neither to linger or say farewell, but went straight from the stadium to the station and took the first train out of Athens".
