Nigel Gaffey (born 5 January 1970) is an Australian former rugby league footballer who played in the 1990s and 2000s.
He played at club level for the Canberra Raiders, the Sydney City Roosters, the South Queensland Crushers and the Penrith Panthers, as a second-row and lock.
A Canberra junior, Gaffey made his first grade debut for the Raiders as a replacement in their 22-16 loss against the Cronulla Sharks at Seiffert Oval in round 16 of the 1989 season.
Gaffey replaced the injured Bradley Clyde in the Raiders' victory over the Penrith Panthers in the 1990 Grand Final.
In 1996, along with fellow Roosters Jason Hudson, Graham Mackay, Clinton O'Brien and Mark Protheroe, Gaffey joined the ill-fated South Queensland Crushers.
