26 27 | | 20 May 2023 | | Aviva Stadium, Dublin | | Jaco Peyper (South Africa) | | Dry with sunny spells |

The 2023 European Rugby Champions Cup Final was the final match of the 2022–23 European Rugby Champions Cup, and the twenty-eighth European club rugby final in general. The final was contested by Leinster and La Rochelle, and a repeat of the 2022 Final which La Rochelle won 24–21.

The Aviva Stadium was the host venue of the final, just the second time it has hosted the game having also been the venue in 2013.

The match referee was Jaco Peyper, the first South African to referee the European showpiece final.

La Rochelle retained the trophy with a 27–26 win over Leinster.

For the first time both finalists from a Champions Cup final returned to the following year's final. La Rochelle became the third team after Toulouse (2003–05) and Toulon (2013–15) to appear in three successive finals, while Leinster, for the second year, attempted to match Toulouse's outright record of five European Champions Cups. This was also the first final since 2011 that matched the top two seeds after the pool stage in the showpiece final.

Both Leinster and La Rochelle entered the final in similar form, with both teams having won every game in their European campaign. They both topped their respective pool, with Leinster gaining a maximum of 20 points and La Rochelle gaining 18. They both received home advantage through the knock-out stage, before gaining home country advantage in the semi-final to see them through to the final.

This was their third meeting in the Champions Cup, with La Rochelle winning both the previous encounters.

Their domestic form saw Leinster enter having lost their United Rugby Championship semi-final the week prior, whilst La Rochelle entered having secured a top two seed in the Top 14 with one round left of the regular season.

Both teams announced their match-day 23 the day before the game and Leinster had two changes to the starting XV that played in the 2022 Final, whilst La Rochelle had seven changes to the team that played in that final.
