William Edward Brennan (10 September 1863 – 8 October 1937) was an Australian politician. He was a member of the New South Wales Legislative Council between 1925 and 1934 and a member of the New South Wales Legislative Assembly from 1934 until 1935. He was a member of the Labor Party (ALP) .
Brennan was born and educated to elementary level in Wallsend, New South Wales. At age 14, he commenced work as a coal-miner at Wallsend Colliery. He was an office-holder in the Colliery Employees Federation from 1903 and in 1909, after leading a strike, he was convicted of conspiracy under the Master and Servant Act and goaled at Bathurst for 3 months. In 1925, after a number of unsuccessful attempts to win the seat of Maitland, Brennan was granted a life appointment to the New South Wales Legislative Council. Brennan resigned this appointment to contest the seat of Hamilton at a by-election caused by the death of Hugh Connell in 1934.
