Firth William McCallum (27 December 1872 – 11 July 1910) was an Australian rules footballer who played with Geelong in both the Victorian Football Association (VFA) and the Victorian Football League (VFL).

[6] He married Jeanetta Gilmore "Nettie" Douglas (1877–1949), at Geelong, on 22 April 1903;[7] they had three children.

[13] On 21 July 1894 he and his Geelong team-mate, Joe Marmo,[14][15] played on the wing for the VFA in an inter-colonial match, against South Australia, on the MCG.

[16] He played for Geelong in its first-ever match in the new VFL competition, against Essendon, at the Corio Oval, on 8 May 1897.

At the end of the 1899 season, in the process of naming his own "champion player", the football correspondent for The Argus, Reginald Wilmot ("Old Boy"), selected a team of the best players of the 1899 VFL competition: From those he considered to be the three best players — that is, Condon, Hickey, and Pleass — Wilmot selected Pat Hickey as his "champion player" of the season.
