Alphonsus "Fonse" John Carroll (20 April 1895 in Mataura – 1 December 1974 in Palmerston North) was a New Zealand dual-code international rugby union and rugby league footballer who played in the 1920s, who represented New Zealand in both codes.

[2] Carroll began playing rugby union aged 22 in 1917 for the Jackeytown club and first represented Manawatu in 1919.

Interviewed after the game he said "there was no loafing in the lineout, but one had to be going all the time" and "intimated the code had come to stay in Manawatu so far as he was concerned".

He participated in some "low level" coaching and was eventually reinstated in 1967, at the time of the NZRFU's 75th jubilee.
