The election of MEPs representing Latvia constituency for the 2004–2009 term of the European Parliament was held on 12 June 2004.

It was significantly lower than the usual turnout for Latvian parliamentary elections (which has been between 71% and 73% for previous three elections) but higher than the turnout in most of other countries which joined EU together with Latvia in 2004.

The election was conducted according to party-list proportional representation system, with at least 5% of votes necessary to gain seats in the parliament.

Tautas Partija was the only coalition party to win a seat.

The exception was Southeast Latvia (Daugavpils, Krāslava and Rezekne districts and cities of Daugavpils and Rēzekne) which were won by the Par Cilvēka Tiesībām Vienotā Latvijā party and Ludza district won by Socialist Party of Latvia, due to large percentage of ethnically Russian voters in this area.
