The Doughty Challenge Shield is a rugby union football trophy in Brisbane, Australia.
Named for businessman Hector R. Doughty, a former Queensland rugby representative, boxer and rower, the Doughty Shield was awarded to the Brisbane A Grade Rugby Union Premiers from 1931 to 1941 inclusive.
The Doughty Shield was later resurrected as a Premier Grade knock-out competition from 1946 to 1951 inclusive.
Since 1957, the shield has been awarded for the club championship in Brisbane, where every team from each club contributes to an overall points tally. In 2007 Premier Rugby was not included in calculations, but this change only lasted for one season.
The champion club is determined by the total accumulation of points from all teams (Premier Grade to 4th Grade, Women and Premier Colts to Colts 2). 5th Grade were included in the Doughty Shield calculations for the first time ever in 2013.
