The Junior Eurovision Song Contest (often shortened to JESC, Junior Eurovision or Junior EuroSong) is an international song competition which has been organised by the European Broadcasting Union (EBU) annually since 2003.

The competition has many similarities to the Eurovision Song Contest from which its name is taken. Each participating broadcaster sends an act, the members of which are aged 9 to 14 on the day of the contest, and an original song lasting three minutes at most to compete against the other participating entries. Each entry represents the country served by the participating broadcaster. Viewers from all around the world are invited to vote for their favourite performances by online voting, and a national jury from each participating country also vote. The overall winner of the contest is the entry that receives the most points after the scores from every country have been collected and totalled. The most recent winner is Lissandro of France, who won the 2022 contest in Yerevan, Armenia, with his song "Oh maman!".

In addition to the countries taking part, the 2003 contest was also broadcast in Estonia, Finland and Germany (who would not debut until the 2020 contest), Bosnia and Herzegovina in 2004 and from 2006 to 2011, followed by Andorra in 2006, and Iceland in 2021, however these countries have yet to participate. Since 2006, the contest has been streamed live on the Internet through the official website of the contest. Australia was invited to participate in the 2015 contest, while Kazakhstan was invited in the 2018 contest, making it the only major Eurovision event to feature multiple associate member broadcasters.
