Alfred James Vincent (9 February 1874 – 6 December 1915) was an Australian cartoonist born in Launceston, Tasmania.
Alf Vincent contributed work to the Melbourne Punch from 1895, in 1896 succeeding Tom Carrington as feature artist. After many years of submitting work to the Sydney Bulletin, he joined their staff in 1898, as a replacement for Tom Durkin and remained there until 1915. He also contributed to The Bulletin's sister publication, Lone Hand.
His work may be mistaken for that of his idol Phil May (1864–1903), a fact that was noted by several critics, including A. G. Stephens and Lionel Lindsay.
He was a member of the Melbourne Savage Club from its foundation in 1900 to 1915 and designed the club emblem.
After some months of ill health, he committed suicide by cutting his throat with a razor.
