The Dublin venue has been chosen to host both the Champions and Challenge Cup Finals.
Dublin's Aviva Stadium will host next season's European Champions Cup and Challenge Cup finals.
The 2023 competitions will be staged on Friday, 19th, and Saturday, 20th May.
It will be the fifth time Dublin has been the host city for a European decider, but it will be Dublin's first final in 10 years.
Next year's showpiece was originally slated for the Tottenham Hotspur Stadium, but changes to the football calendar has resulted in tournament organisers selecting Lansdowne Road as the designated ground.
