Thomas Mark Bishop (born 29 June 1954) is a former Australian politician who served as an Australian Labor Party member of the Australian Senate representing the state of Western Australia from July 1996[1] until June 2014.

He was an industrial officer and union secretary before entering politics.

In December 2006, Bishop announced that he would not recontest his Senate seat, due to expire on 30 June 2008.

However, before the 2007 he decided to recontest and was re-elected for a further six-year term.

Bishop withdrew from Senate preselection for the 2014 election after a factional deal which would have seen him relegated to an unwinnable position on the ticket.
