Wiliam A. Cann (1882–1958) was an Australian rugby league footballer who played in the 1900s who later wrote for The Sydney Morning Herald.

[3] Cann played his club football for South Sydney with whom he won the 1914 NSWRFL Premiership.

Cann, a contemporary of Dally Messenger and Albert Rosenfeld, began his playing career as a Rugby union three-quarter at Souths.

Butler was then selected to tour England with the Kangaroos in the 1908–09 so was unable to play in Souths' first premiership win in 1908.

In 1921–1922, Cann was co-manager of the Kangaroo tour along with Souths' secretary, S. G. "George" Ball.
