Sean Scully (born 28 September 1947) is an Australian actor, active in film and television, most especially serials.

Scully was born in Sydney, New South Wales. He began his acting career at the age of 12, going on 13, in the 1960 Children’s Film Foundation film Hunted in Holland, which won the Diploma of Honour at the Cannes Film Festival. Following that, he was signed by Walt Disney and starred in a number of Technicolor family feature films for the studio, including The Prince and the Pauper (filmed 1961, released 1962), in which he played both title characters, alongside Guy Williams as Miles Hendon, and also played opposite Patrick McGoohan in Dr. Syn, Alias the Scarecrow (1963).

Scully also starred in the 1962 Walt Disney movie Almost Angels. He played Peter, a member of the Vienna Boys' Choir whose voice is near to breaking. He is extremely jealous of Toni Fiala, played by Vincent Winter, who is the new boy with a wonderful clear treble voice. Ultimately, however, the two boys become friends. The film was retitled Born To Sing in the UK.
