Clarence Gordon Robertson (9 April 1902 – 31 October 1974) was an Australian politician and a member of the New South Wales Legislative Assembly between 1942 and 1950 and again between 1953 and 1959.
He was educated to elementary level in Dubbo and, from the age of 14, worked as a rural labourer.
Despite a resurgence in rural support for Labor at the election, Robertson was defeated by the incumbent Country Party member George Wilson by 159 votes.
Wilson died 11 months after the election and Robertson won the resultant by-election.
Robertson regained the seat in 1953 and retained it until he was defeated at the 1959 election by the Liberal Party's, Les Ford.
