Harold William Crommelin (9 April 1903 – 20 May 1998) was an Australian businessman and politician who was a Liberal Party member of the Legislative Assembly of Western Australia from 1956 to 1968, representing the seat of Claremont.
One of those was the incumbent member, Charles North, who had held the seat for 32 years and was also a former Speaker of the Legislative Assembly.
[3] Crommelin was re-elected unopposed at the 1959 election and was subsequently made deputy chairman of committees in the Legislative Assembly.
He held that position until his retirement at the 1968 election, which coincided with an electoral redistribution that abolished the seat of Claremont.
[1] At the time of his death, only one other MP in Western Australia (Sir Leslie Diver) had lived to a greater age.
