The 2023 Super League Grand Final, was the 26th official grand final, and championship-deciding rugby league game of Super League XXVIII. The match was contested between Wigan Warriors and Catalans Dragons, at Old Trafford.

St Helens were the defending champions, having won 4 consecutive titles in 2019, 2020, 2021, and 2022, but they were eliminated in the Semi-final, losing 6–12 to Catalans Dragons in a repeat of the 2021 Final, which St Helens won 12–10.

Catalans ended the regular season in 2nd place, thus earning them a bye to the semi-finals, where they would play the highest ranked winner of the eliminators, which was St Helens. Catalans thought they had scored the first try of the game on 18 minutes, as Tom Johnstone touched down in the corner, but the referee decided the on field decision was NO TRY, with the video referee confirming this, as Johnstone was deemed to have pushed Jonny Lomax off the ball, while chasing the kick. St Helens then got possession back, with Lewis Dodd putting a high kick up. As the ball bounced, Tom Johnstone somehow fumbled it 20 metres out, attempting to pick the ball up. On 28 minutes, Catalans were awarded a penalty, as Sione Mata'utia was penalised for a high tackle on Sam Tomkins, with Catalans opting to kick for goal. Adam Keighran successfully kicked the goal, to give Catalans a 2–0 lead with 10 minutes until half time. The first TRY of the game, came on 50 minutes, as Catalans knocked on, inside their own 40-metre line, and Will Hopoate touched down next to the posts. Mark Percival successful with the conversion, and St Helens lead 6–2. Catalans were awarded another penalty on 64 minutes, as Moses Mbye was penalised for a high tackle. Despite being 4 points down, Catalans opted to go for the 2 points, to which Keighran was successful again, and Catalans were back to within 2 points. With 8 minutes of the match remaining, things got worse for St Helens, as Matty Lees was sent to the sin bin, for what seemed to be holding down on Tom Johnstone, but replays show that his leg was trapped in the tackle. Keighran again opted to kick for goal, to which he was successful, and both teams were level at 6–6. On 75 minutes, Saints knocked the ball on, near the halfway line to give Catalans possession 40 metres out. 2 minutes later, Tomkins looked like he was going for a drop goal attempt, but decided to run with the ball. From the resulting kick through, saints had to clear the ball for a goal line drop out. With 3 minutes remaining, Tomkins attempted to kick a drop goal, but his effort was short, and saints got the ball back, only for Mata'utia to drop the ball 20 metres out. As the game looked to be heading to extra time, Sam Tomkins scored the winning try, with less than 1 minute remaining, and hand saints their first play-off defeat since 2018. Final score: Catalans 12–6 St Helens
