Alfred Reginald Fremlin (1832 – 14 July 1915) was an English-born Australian politician.

He was born in Wateringbury in Kent to William Fremlin and Elizabeth Morton. A fellmonger, he married Elizabeth Mennons around 1852; they had twelve children. He migrated to New South Wales around 1855 and settled in Sydney, working as a fellmonger; he would later become a Baptist minister. In 1880 he was elected to the New South Wales Legislative Assembly for Redfern. Re-elected in 1882, he did not contest in 1885, although he ran again unsuccessfully in 1887, 1889 and 1891. Fremlin died at Enfield in 1915.^[1]
