The 2003–04 European Nations Cup was the fourth edition of the newly reformed European Championship for tier 2 and 3 rugby union nations. This was the second two-year cycled championship, the first to be planned from the start.
The title was won by Portugal for the first time, with their Iberian neighbours Spain being relegated. Portugal won all their games, except to a loss abroad to Romania. The Championship saw another new face in the Czech Republic who replaced the relegated Netherlands.
