The 2021–22 Rugby Europe International Championships is the European Championship for tier 2 and tier 3 rugby union nations.

The 2021–22 season is the fifth of its new format and structure, where all Levels play on a one-year cycle, replacing the old format of a two-year cycle, with the teams playing each other both home and away.

For all teams competing in the Championship, this year's edition of the Rugby Europe International Championships doubles as the second year of 2023 Rugby World Cup qualifiers for the European region, where the winner and runner-up teams of the two-year cycle, automatically qualifies to the tournament as Europe 1 and Europe 2.

The third team qualifies to the Final qualification tournament.
