Kenneth Edward "Ken" Vowles (born 29 September 1971) is an Australian politician and former cricketer from the Northern Territory.
Born in Darwin, Vowles attended the Australian Cricket Academy on a scholarship from 1989 to 1990, during which time he toured internationally with the Australian Under-19 team. As an Under-19 player, Vowles held the record for the fastest century scored at the Melbourne Cricket Ground until the record was broken by Viv Richards.
In 2008, Vowles contested the seat of Blain as an Australian Labor Party candidate at that year's Territory general election, although he was defeated by Terry Mills, then future Chief Minister. He nominated to contest the seat of Johnston in the 2012 election, although a controversy emerged when the Labor Party threatened the Northern Territory News with legal action to prevent the newspaper from publishing a story about Vowles' spent assault conviction from a fight in 1992 (Labor leader Paul Henderson had previously been critical of another candidate for not disclosing a manslaughter conviction).
Vowles was elected as member for Johnston, although the Henderson government was defeated by the Country Liberal Party.
