The 2004 European election was the sixth election to the European Parliament. However, as Estonia had only joined the European Union earlier that month, it was the first election European election held in that state. The election took place on 13 June.
The biggest winner was the Social Democratic Party. The governing Res Publica Party and People's Union polled poorly. The voter turnout in Estonia was one of the lowest of all member countries at only 26.8%. A similar trend was visible in most of the new member states that joined the EU in 2004.
