Anthony Gelling (born 18 October 1990) is a Cook Islands international rugby league footballer who plays as a centre, winger and second-row forward.

In 2016 he refused to apologise for saying that some of the refereeing decisions "pissed me off" in a post match interview on Sky Sports, instead declaring "I speak my mind.

He didn't score again until the match against Huddersfield on 11 August before finishing the season with a try against rivals St. Helens and a brace against Hull FC.

[16] He reported back to Wigan for preseason in preparation for the 2018 Super League season but not long after he asked for a release from his contract after his girlfriend was involved in a car crash.

[18] Gelling returned to play Super League, signing a two-year deal with Warrington after his contract in New Zealand expired.

On 18 May 2021, he was found not guilty of inflicting grievous bodily harm on his former partner, after a jury took just over four hours to deliberate, before acquitting him of the charge following a three-day trial at Liverpool Crown Court.

On 17 October 2015, Gelling played for the Cook Islands in their Asia-Pacific Qualifier match against Tonga for the 2017 Rugby League World Cup.

This resulted in coach Tony Iro selecting him to be part of the Cook Islands team for the Delayed 2021 Rugby League World Cup.

Following their second group stage match against Papua New Guinea, Gelling announced his retirement from rugby league for a second time.
