Neville Costigan (born 16 March 1985) is a Papua New Guinean former professional rugby league footballer who played in the 2000s and 2010s.

A Papua New Guinea international and Queensland State of Origin representative forward, he played in the National Rugby League for Australian clubs the Brisbane Broncos, the Canberra Raiders, the St. George Illawarra Dragons (with whom he won the 2010 NRL Grand Final) and Newcastle Knights.

On 13 August 2008, Costigan signed a 2-year contract with the St. George Illawarra Dragons starting in 2009, re-joining the coach that sacked him from the Brisbane Broncos, Wayne Bennett.

I had other options but I like the town, the lifestyle it offers, their fanatical supporters and the fact I can play a part in the direction the club is heading over the next couple of years.

On 22 July 2013, Costigan signed a 2-year contract with Super League side the Hull Kingston Rovers starting in 2014, re-joining former Knights assistant coach Craig Sandercock.
