George Wells Smailes (1 January 1862 – 9 January 1934) was an Australian politician in the New South Wales parliament, representing the electoral district of Granville for Labor from 17 July 1894 to 5 July 1898, and was a Methodist minister. Later he was an Anglican vicar in New Zealand, and a chaplain with the New Zealand garrison in Samoa in World War I. He apparently changed his surname from Smailes to Wells-Smailes in New Zealand. He was born in Durham, England. He moved to New South Wales in 1882, and to Sydney in 1891.
