Gavin Miller is an Australian former rugby league footballer who played in the 1970s and 1980s. An Australian international and New South Wales State of Origin representative forward, he played the majority of his club football for the Cronulla-Sutherland Sharks, and is an Immortal of the club. He earned two successive Dally M Player of the Year awards in 1988 and 1989.

At his peak, Miller was regarded by many pundits as the most dangerous attacking forward in the NSWRL, largely due to his ball playing and kicking skills. Miller's influence was at the helm of the Cronulla-Sutherland becoming Premiership contenders after having spent some years at the lower end of the ladder. During Miller's heyday, Australian selectors were often criticised for ignoring him, notwithstanding that Miller did not show the best of his skills in a badly beaten New South Wales side during the 1989 State of Origin series.

Gavin Miller was born in Inverell, New South Wales. Before his late-1980s fame, Miller had already a long career in rugby league. He began playing for Goulburn as a centre and was recommended to Western Suburbs in 1977. That year, he obtained a regular place in the team at the age of seventeen but was signed by Eastern Suburbs the following year. Miller did poorly for Easts in the following two years but Cronulla thought he had potential and signed him for 1980.

Still playing as a centre, Miller obtained a regular place in the Cronulla side and gradually showed he had exceptional ball skills as well as the ability to run which he had shown with Wests. Over his first four years at Cronulla he was moved into the forwards and did so well that by 1983 he was chosen to play for New South Wales. Miller did not fulfil expectations there and during the season was involved in a dispute with the Sharks' committee – he had said he would leave the financially crippled club if it did not win the KB Cup. The Sharks failed to do this, and Miller was sacked at the beginning of October. That November Miller was signed by his former club Eastern Suburbs.

After leaving Easts, Miller signed to English club Hull Kingston Rovers. During his three year stint with Hull KR, Miller received many awards. Miller won the Man of Steel award for the 1985–86 Rugby Football League season.

Miller returned to Cronulla in 1986 a more mature player, and after a slow start to his second stint with the club, by 1988 Miller had become one of the most dominant players in the ARL. He had the ability to consistently offload and send players into gaps, and was at the helm of Cronulla winning fifteen of their last seventeen home-and-away matches, and claiming the club’s first minor premiership.

Despite not playing for New South Wales against either Queensland or Great Britain, Miller's club form was enough that selectors did not ignore him for the Test against Papua New Guinea. In a world international rugby league record 70–8 win, Miller "launched countless raid on the Kumuls' line"and scored a try.

1989 was Miller's greatest year, and he monopolised the player-of-the-year awards like no other player except perhaps Peter Sterling and latterly Andrew Johns. His brilliant ball-playing skills were by now backed up with a superb kicking game, a high work-rate in defence and the ability to take the knocks that came from being a focal playmaker. He won not only the Dally M Player of the Year, but also the Rugby League Week Player of the Year and the Rothmans Medal. His form against Brisbane in the play-off for fifth was described as "mesmerising" and saw the Sharks win 38–14.

In 1990, with injuries contributing to slow his body, saw Miller decline somewhat, though in two games against Balmain and South Sydney he showed he could still be as skilful as ever. At thirty, though, he was out of contention for the Kangaroo tour, and the following year, with the responsibility of captaincy, saw Miller decline further. In 1992, with the changing of the guard at Cronulla, he was surprisingly relegated to reserve grade, but still showed his old skill in patches when brought on for the first team. After his retirement from first grade rugby league, Miller was named as one of the five "immortals" of the Cronulla club.

Miller remains unique in having won the Man of the Match award in the 1985–1988 Rugby League World Cup Final against New Zealand in 1988, the Man of Steel award, the Dally M Awards Player of the Year, the Rugby League Week Player of the Year and the Rothmans Medal.
