Gorden Tallis, also known by the nickname of "Raging Bull” for his on-field aggression, is an Australian former professional rugby league footballer who played in the 1990s and 2000s. He is currently a commentator and pundit for the Fox Sports network. A Queensland State of Origin and Australian international representative second-row forward, he captained both these teams as well as the Brisbane Broncos with whom he won the 1997, 1998 and 2000 Grand Finals, after starting his career with the St. George Dragons in Sydney. At the peak of his career Tallis was considered as the best second-row forward in the world and in 2008 was named in an Indigenous Australian rugby league team of the century.

Tallis was born in Townsville, North Queensland on 27 July 1973. There he played for the Centrals Tigers club. Tallis' father Wally played rugby league briefly for Leigh in the 1960s, and was the captain of an Indigneous rugby league team that toured New Zealand in 1972.

Tallis moved to Sydney to make his first grade debut in the Winfield Cup premiership for St. George on 29 August, 1992, aged 19. In 1992 Tallis played for NSW City under 19s and NSW Under 19s. He was a reserve in St George's 1993 grand final loss to Brisbane. Tallis was used to bad effect off the interchange bench during the 1994 season and also made his representative debut for the Queensland side in the final two State of Origin series games that year.

When the proposed Super League competition was put on hold in 1995, Tallis offered to buy out the final year of his contract with St. George in order to join Brisbane. St. George declined the offer however, and subsequent court action held him to his original contract. Having already signed a Super League contract to play with Brisbane, the fiery North Queenslander caused controversy when he was the only player who chose to sit out the 1996 season rather than play a final year with St. George. After having made 54 appearances for the Red V, he left Sydney.

Tallis returned to the game with the Broncos for the 1997 Super League season and was the most dominant forward in the competition, which culminated in Brisbane's crushing 26–8 win over the Cronulla-Sutherland Sharks in the Telstra Cup grand final. In addition to representing Queensland in the Super League Tri-series competition, he made his international debut in the 1997 post season's Super League Test series against Great Britain, playing at second-row forward in all three matches.

In 1998 Tallis returned to St. George for the first time since his acrimonious split with the Saints and was pelted with garbage and insults and was loudly booed every time he touched the ball before his try secured a 30–18 victory. Brisbane went on to capture another premiership with Tallis scoring a try and winning the prestigious Clive Churchill Medal as the best and fairest player on-field in the club's 38–12 1998 NRL grand final win over the Canterbury Bulldogs. Tallis made his Australian Kangaroos Test debut in the second match of the Trans-Tasman series.

He continued his great personal form when chosen for the ANZAC Test in 1999 and spearheaded Queensland's State of Origin campaign in a historic tied series. However, the season ended with Brisbane's failure to defend its premiership and Tallis was ruled out of October's Tri-Nations competition because of injury.

If Tallis' stature as the most dominant forward in the game wasn't secure following Brisbane's 14–6 win over the Roosters in the 2000 NRL grand final, his four tries in Australia's 82–0 humiliation of Papua New Guinea before the 2000 World Cup, and his selection as Australian captain for the match against Russia (which resulted in a record 110–4 victory) did.

Tallis made a strong return to football in 2002 after a career threatening neck injury. It was in the deciding match of the 2002 State of Origin series that Gorden Tallis performed a famous tackle on Blues fullback, Brett Hodgson, dragging him several metres and eventually tossing him out of the field of play like a rag-doll. Tallis' reaction later of giving the one-finger salute to a section of the crowd, right behind the northern try-line where Dane Carlaw's series-tying try was scored, became a major after-match talking point.

At the end of 2003, Tallis, who was expected to lead Australia on the 2003 Kangaroo tour announced his retirement from representative football, but continued playing with the Broncos. In 2004 he started to feel more affected by his neck injury and took heed of the warning signs his body was emitting. He played his last official match in the 2004 semi-final for the Brisbane Broncos, fittingly in his hometown of Townsville, against the Cowboys, which the Broncos lost. At the time of his retirement, he held the Broncos' club record of most career tries for a forward.

In 2018, Tallis was inducted into the Australian Rugby League Hall of Fame. Tallis co-hosts Triple M Radio Brisbane's sports segment where he regularly amuses listeners with nonsensical opinions on the game. In 2024, Tallis joined NRL 360 on Fox League replacing Paul Kent.
