Thomas Armstrong (13 September 1903 – 16 March 1957) was an Australian politician.
He was independent but generally supported the Labor Party government of Joseph Cahill.
Armstrong was born and educated to elementary level in Lambton, New South Wales.
He was the son of a coal-miner and began working as a miner at Wallsend Colliery at age 14.
Armstrong was elected as the member for Kahibah at a by-election,[1] caused by the resignation of Joshua Arthur who was found guilty by a Royal Commission of improper business dealings.
