Rodney 'Balls' Grinter (born 26 May 1965) is a former Australian rules footballer who played for Melbourne in the VFL and AFL.
Later that season he appeared in Melbourne's losing Grand Final side against Hawthorn.
Melbourne led by 4 points with only a few seconds remaining when Grinter conceded a free kick to Gary Buckenara fifty metres from goal.
As Grinter stood on the mark, his teammate Jim Stynes ran between him and Buckenara and the siren sounded.
Grinter was coach of New Norfolk in the Tasmanian Statewide Football League during the 1996, 1997 and 1998 seasons.
