The 2023 Rugby Europe Championship was the seventh Rugby Europe Championship, the annual rugby union for the top European national teams outside the Six Nations Championship, and the 53rd edition of the competition (including all its previous incarnations as the FIRA Tournament, Rugby Union European Cup, FIRA Nations Cup, FIRA Trophy and European Nations Cup).

Eight teams took part in the 2023 Championship, up from six in previous tournaments, due to a reorganisation of the various flights of European international competition.

The Championship was contested by Belgium, Georgia, Germany, Poland, the Netherlands, Portugal, Romania and Spain.

Russia, who competed in the 2022 Championship were relegated as a result of suspension due to their country's 2022 Russian invasion of Ukraine.
