William John Vowles (22 April 1876 – 21 August 1943)[1] was a solicitor and member of the Queensland Legislative Assembly.

He started his legal career as an articled clerk with J.B. McGregor in Brisbane and, after being admitted to the bar, he moved to Dalby in 1899, where he set up his own practice.

He was interested in the public affairs of Dalby and was a member of several clubs and was also on the hospitals' board for forty years.

He did not attend his office the next day and was resting in bed when he suffered another heart attack, this time fatal.

He resigned from the council when he became opposition leader in the state parliament, but he resumed as an alderman after he lost his seat after in 1926.
