20 venues in 15 countries have hosted the Junior Eurovision Song Contest, an annual song competition for children, at least once since its creation in 2003. The first edition took place in Copenhagen, Denmark. Following the hosting problems for the 2004 edition, the location of the subsequent contests were appointed by the European Broadcasting Union (EBU), following a bidding process among the participating broadcasters. The broadcasters from Belgium were therefore the first to successfully bid for the rights to host the contest in . Poland became the first country to host two contests in a row (in 2019 and in 2020, respectively).
Originally, unlike its adult version, the winning broadcaster does not receive the rights to host the next contest. However from 2014 to 2021 (excluding 2018), the winning broadcaster had first refusal on hosting the next competition. (RAI) used this clause in 2015 to decline hosting the contest that year after their victory for Italy in .
The cities that have hosted, or are scheduled to host the contest twice, are Kyiv (2009 and 2013), Minsk (2010 and 2018), Yerevan (2011 and 2022), and Tbilisi (2017 and 2025).
