Solomon Haumono (Tongan: Solomone Haumono; born 13 October 1975) is a former professional boxer and former rugby league footballer of Tongan descent.

He attended Newtown Boys High School, Newtown, New South Wales. He then went on to Christian Brothers' High School, Lewisham and represented them in the New South Wales Combined Catholic Colleges Australian Schoolboys team 1993.^[2]

In rugby league, his preferred position was second-row. He played in the NRL for the Manly-Warringah Sea Eagles, the Canterbury-Bankstown Bulldogs, the Balmain Tigers, the St George Illawarra Dragons, and in the Super League for the London Broncos/Harlequins RL. Haumono played at representative level for New South Wales and Australia, although these three state matches and one international match were in 1997, when Super League contracted players were ineligible for State of Origin selection. He also captained Tonga.

Haumono made his first grade debut for Manly-Warringah in round 11 1994 against Balmain, coming off the bench in a 42–0 victory at Leichhardt Oval. In 1995, Haumono featured heavily in the Manly side which won the minor premiership having lost only 2 matches all year. Haumono played from the bench in Manly's shock grand final loss to Canterbury. In 1996, Haumono played 14 games but missed out on selection in Manly's premiership winning side which defeated St. George in the grand final.

In 1997, Haumono signed with Canterbury who aligned themselves with the rival Super League competition during the Super League war. During the 1998 NRL season, Haumono walked out on Canterbury midway through the year after devising a plan to get out of his contract with the club. Haumono's plan was to join his supposed girlfriend Gabrielle Richens in England. Haumono elaborated on the plan saying I was under contract for the Bulldogs so it was decided to come up with a plan that would ultimately force the Bulldogs to rip up my contract, So the plan was formed that I was going to chase after my girlfriend at the time in England. So off I went and before I knew it, the paper got a hold of it and blew it up, making headline news and myself being chased by the media at home and even there in London".^[3]

The plan was devised by Haumono and close friend Anthony Mundine but fell over when Canterbury got wind of the plot and instead fined Haumono and put him in reserve grade.^[3]

In 1999, Haumono signed with Balmain. Haumono only made 8 appearances for Balmain due to an elbow injury. In 2000, Haumono joined St George but only featured in 2 games, the last of which was the club's humiliating 70–10 loss against Melbourne at the Melbourne Cricket Ground.^[4]

Haumono is married to Margaret, who is a cousin of his friend and fellow rugby league player-turned boxer Anthony Mundine. Solomon and Margaret have five children.^[9]

He dated English model Gabrielle Richens for a period of time during his time with Canterbury.

In 2015, Haumono revealed he had been suffering a drug addiction during his league career. He was addicted to ice, cocaine and ecstasy.^[10]
