The Eurovision Song Contest 2003 was the 48th edition of the Eurovision Song Contest, held on 24 May 2003 at the Skonto Hall in Riga, Latvia, and presented by Marie N and Renārs Kaupers. It was organised by the European Broadcasting Union (EBU) and host broadcaster Latvian Television (LTV), who staged the event after winning the 2002 contest for Latvia with the song "I Wanna" by Marie N. Kaupers had also represented Latvia in 2000 as a member of Brainstorm.
Broadcasters from twenty-six countries participated in the contest, beating the record of twenty-five first set in 1993. It saw the return of Iceland, Ireland, the Netherlands, Norway, and Poland after having been relegated from competing the previous year. Portugal also returned to the contest after being absent the previous year, while Ukraine participated in the contest for the first time. Denmark, Finland, Lithuania, Macedonia, and Switzerland were relegated due to their poor results in 2002.
