Albert Ernest Thomas (10 March 1872 – 25 May 1923) was a member of the Legislative Assembly of Western Australia from 1901 to 1905, representing the seat of Dundas.
He attended the Camborne School of Mines, and afterward worked as a mining engineer in Cornwall, Wales, and South Africa.
Thomas came to Western Australia in 1896, and subsequently managed mines in Norseman and Coolgardie.
At the early 1905 election, however, he was defeated by a Labor candidate, Charles Hudson.
Thomas recontested Dundas at the 1908 election, but again lost to Hudson.
