William Anderson (14 January 1868 – 16 August 1940) was a notable Australian theatre entrepreneur.
He left school at age ten and eventually found work as a theatre manager, marrying the actress Eugenie Duggan.
He established two theatre companies, opened Wonderland City in Sydney and built the Kings Theatre in Melbourne.
He produced several classics of the Australian stage including Thunderbolt (1905), The Squatter's Daughter (1907) (which he filmed in 1910) and The Man from Outback (1909), as well as co-writing several plays.
Anderson worked with such actors and writers as Edmund Duggan, Bert Bailey, Olive Wilton and Roy Redgrave and for a time his private secretary was Beaumont Smith.
The financial failure of Wonderland City cost him his personal fortune, but he remained involved in theatre productions until the end of his life.
