Gordon Edgar Masters (born 30 August 1931) is a former Australian politician who was a Liberal Party member of the Legislative Council of Western Australia from 1974 to 1989, representing West Province.
He attended Berkhamsted School and the Hertfordshire Agricultural College, and then farmed locally until 1962, when he emigrated to Australia.
Living on the outskirts of Perth, Masters purchased a contracting business, and later diversified into beef farming.
Masters entered parliament at the 1974 state election, winning his seat from the Country Party.
He held those positions until the government's defeat at the 1983 state election, and remained in the shadow cabinet until his retirement at the 1989 election, serving under three different leaders of the opposition (Ray O'Connor, Bill Hassell, and Barry MacKinnon).
