The Canberra Raiders are an Australian professional rugby league football club based in the national capital city of Canberra, Australian Capital Territory. They have competed in Australasia's elite rugby league competition, the National Rugby League (NRL) premiership since it started in 1998, they were included in the NSWRL from 1982. Over this period the club has won three premierships out of six Grand Finals, the last one played being the 2019 NRL Grand Final, resulting in a 14-8 loss to the Sydney Roosters. Canberra currently have the second longest active premiership drought in the NRL totalling over 30 plus years. The Raiders' current home ground is Canberra Stadium in Bruce. Previously, the team played home matches at Seiffert Oval in Queanbeyan, New South Wales, with the move to the Canberra Stadium in Bruce taking place in 1990. The official symbol for the Canberra Raiders is the Viking. The Viking, also a mascot at Raiders' games, is known as Victor the Viking.

As part of the New South Wales Rugby Football League premiership's first expansion outside Sydney, the Raiders were admitted to the League, along with the Illawarra Steelers in the 1982 season. Over the following years they improved steadily, reaching a playoff for 5th in their third season, and becoming the first non-Sydney team to make the finals (1987), after this they would go on to feature in a grand final (1987) and win a premiership (1989). This heralded a period of great success for the club, with five grand Final appearances and three premierships in eight years. During this period, the Raiders boasted international players such as Mal Meninga, Laurie Daley, Ricky Stuart, Glenn Lazarus, Bradley Clyde, Gary Belcher, Brett Mullins and Steve Walters. After this came the Super League war, with the Raiders switching to the rebel competition before continuing to compete in the re-unified NRL. During the 2000s, the Raiders suffered from an exodus of experience. At the beginning of the 2009 season, the Raiders squad contained only four players who had played at the representative level. Joel Monaghan and Terry Campese each represented the Australian side during the 2008 Rugby League World Cup, with Monaghan also playing for the NSW blues during the third game of the 2008 State of Origin series.

At the beginning of the 1980s, the New South Wales Rugby Football League (NSWRFL) was looking to expand its Sydney-based premiership into other areas of the state. The Queanbeyan Blues rugby league team who was coached by Colin O'Rourke at the time was selected to form the Canberra franchise. The Canberra franchise was accepted in 1981 as the 14th team for the 1982 NSWRFL season. Along with the Illawarra Steelers who were also introduced that season, they became the first NSWRFL club based outside Sydney since the old Newcastle team left in 1909.

The club's initial seasons were a mixed bag, with the team earning the wooden spoon in their debut year. The team was notorious for late game collapses, leading to the nicknames "Canberra Faders" and "Pine Lime Splices", in what was also a reference to the team's colours. In fact, no team has conceded more tries in a season than the 1982 Raiders. The first points recorded by the Raiders were scored by Peter McGrath, who went on to score 41 points in his first and only season with the Raiders. The club's first win, a 12–11 heartstopper against Newtown, came in its 8th match, and three more wins followed, most notably against then competition leaders Souths. 1983 saw 9 wins, more than doubling 1982's four. However, the team continued to struggle to win away from home. An away win first up in 1984 foreshadowed a much improved season, a positive winning record (13–11) snagging a playoff for fifth against South Sydney. But this game was lost (4–23), and Canberra had still not succeeded in reaching the semi-finals of the competition.

1985 saw regression, with the team winning only eight games (though the reserves did reach the Grand Final). Though 1986 was similarly disappointing, the team had a core group of players, such as Queensland trio Mal Meninga, Gary Belcher, Steve Walters, and John Ferguson who would greatly influence the coming decade.

This was the most successful period in the Raiders' short history, with five Grand Finals and three premierships. In 1987, the team finished third after the minor rounds, resulting in a maiden semi-finals appearance. Despite going down 25–16 in their first finals match against Eastern Suburbs, Canberra rallied to defeat South Sydney (46–12) and Easts again (32–24) in the Preliminary Final. The latter earned the team a place in the Grand Final, but they were never really competitive against minor premiers Manly-Warringah, going down 18–8 in what was the last Grand Final to be played at the Sydney Cricket Ground. The GF attracted a then Raiders all-time record attendance of 50,201 which would stand until 2019. Laurie Daley, Peter Jackson and Glenn Lazarus all made their debut for Canberra in 1987, though only Queensland State of Origin Centre Jackson played a prominent role that year, more so after his centre partner Meninga broke his arm and missed half of the season.

1988 featured free-scoring (over 100 tries in 22 games) and a number of large victories, with the team again finishing in third place on the ladder. Unfortunately, a narrow 19–18 loss against eventual premiers Canterbury-Bankstown in the Major Semi-final was followed by defeat against the Balmain Tigers and an early exit. After the debuts of Daley, Jackson and Lazarus in 1987, 1988 saw the debuts of future internationals Bradley Clyde, and former Wallaby scrum half, Queanbeyan born Ricky Stuart.

With 5 rounds to play in the 1989 season, Canberra were 7th and in danger of missing the semis. But a hard-fought 14–10 win over the Eastern Suburbs Roosters started a nine-match winning streak, culminating in the club's first Premiership. Throughout the finals, Canberra was forced to walk the sudden-death tightrope after sneaking into the finals in fourth place. They easily accounted for the Cronulla Sharks 31–10 in the Qualifying final, before defeating the emerging Penrith Panthers 27–18 in the semis. Then the Preliminary final, Canberra defeated the minor premiers the South Sydney Rabbitohs 32–16 to qualify for their second Grand Final appearance in three seasons.
