Nathaniel Joseph McAvoy (born 31 December 1976) is an English former professional rugby league footballer who played as a centre or wing.

He spent most of his club career with Salford (1994–98 and 2004–05) and Bradford Bulls (1998–2002 and 2007), but also had short spells with Leeds Rhinos, Wigan Warriors and Leigh Centurions.

During his time at Bradford he lifted the Rugby League Challenge Cup, and the Grand Final in which he scored a spectacular try against bitter rivals Leeds Rhinos in 2000 which is remembered fondly by fans.

Nathan left Bradford and decided it was time for a new challenge and changed codes to play rugby union for Saracens during the 2003–04 season.

His rugby union career was frustrating with an early injury causing loss of form and only made a handful of appearances before joining Salford again mid-2004.
