Follett Johns Thomas (21 October 1863 – 3 January 1942) was an Australian politician.
He was born at Majors Creek, near Araluen in New South Wales, to Richard Uren Thomas and Mary Ann Johns.
The family moved to Inverell around 1871 and Thomas attended the public school there before apprenticing to a chemist in Glen Innes.
In 1903 he was elected to the New South Wales Legislative Assembly as the Liberal member for Glen Innes, moving to Gough in 1904.
He held the seat until the introduction of proportional representation in 1920, when he was defeated running for Northern Tableland as a Progressive.
