John Hynes (born 23 February 1979) is a former Australian rules footballer who played with Carlton in the Australian Football League. Drafted in 1997, Hynes debuted the following year. Playing as a key position player at 184 cm, Hynes often had to play on much larger opponents. As a result, Hynes only managed four senior games in 1998, although he did win the reserves best and fairest award. After failing to play a senior match in 1999, Hynes was delisted by Carlton. He went on to play for Frankston in the Victorian Football League.
Hynes was named Frankston Reserve Team Coach for the 2004 Season.
