Mosese "Moses" Suli (born 9 June 1998) is a Tonga international rugby league footballer who plays as a centre and winger for the St. George Illawarra Dragons in the National Rugby League (NRL).

Suli previously played for the Wests Tigers, was signed by the Canterbury-Bankstown Bulldogs before his contract was terminated ahead of the 2018 NRL season for repeated indiscretions during pre-season, he then joined Manly Warringah Sea Eagles.

Suli was born in Geelong Crescent in St John's Park Fairfield, New South Wales, Australia. He is of Tongan descent.

He played his junior rugby league for Fairfield United. He was then signed by the Wests Tigers. Suli later said, "I got axed by Parra in Harold Matthews when I was 16. They actually wanted me back but I just didn’t want to go back. I just said I wasn’t interested. I was going good at the Tigers and I just wanted to stay here."

In 2016, Suli played for the Wests Tigers' NYC team.

In January, Suli re-signed with the Tigers on a three-year contract until the end of 2020.

In round 1 of the 2017 NRL season, he made his NRL debut for the Tigers against the South Sydney Rabbitohs, scoring a try. The Daily Telegraph said, "Apart from owning wonderful speed, footwork and vision, Suli is also larger than your favourite reality TV star’s ego. Truly, this young bloke is the real deal. A genuine Next Big Thing."

On January 31, Suli was released by the Wests Tigers. It was reported that Suli would only attend training sessions for five minutes, and would sleep in a teammates car while the team was training.
