The Junior Eurovision Song Contest 2019 was the seventeenth edition of the Junior Eurovision Song Contest, held on 24 November 2019 at the Gliwice Arena in Gliwice, Poland, and presented by Ida Nowakowska, Aleksander Sikora, and Roksana Węgiel. It was organised by the European Broadcasting Union (EBU) and host broadcaster Telewizja Polska (TVP), who staged the event after winning the 2018 contest for Poland with the song "Anyone I Want to Be" by Roksana Węgiel. It was the first time that the contest was hosted in Poland, as well as the first Eurovision event to be held in the country since the Eurovision Young Dancers 2013.

Broadcasters from nineteen countries participated in the contest, with Spain taking part for the first time since 2006, while Azerbaijan and Israel did not return to the contest after having participated in 2018.

The winner was Poland with the song "Superhero" by Viki Gabor, making Poland the first country to win the Junior Eurovision Song Contest two years in a row and the first country to win on home soil. Kazakhstan placed second, their best result. Returning country Spain placed third. The Netherlands and France completed the top five.

The 2019 contest took place in Poland for the first time, following the country's victory at the 2018 edition with the song "Anyone I Want to Be", performed by Roksana Węgiel. It was the sixth time that the contest had been hosted by the previous year's winning country. The contest took place in Gliwice Arena, a sport and entertainment hall with a capacity of 17,178 in the main arena. It is considered one of the mixed uses venue in Poland.

Prior to Poland's confirmation two other countries had announced their intentions to host the event. These bids were from Armenia and Kazakhstan. Had the Kazakh proposal been accepted, it would've marked the first time an associate member was chosen to host an EBU flagship event. Kazakh broadcaster Khabar Agency said they would have moved the contest to October due to possible adverse weather conditions in the country's capital Astana, which was proposed as the host city. However, for this to happen, the general rules of the competition would have to be changed, because as in the adult competition, the competition cannot be held in a non-full member state of the EBU, even if the country in question is an effective participant of the contest.

After Poland's victory in the 2018 contest, the director-general of Polish broadcaster Telewizja Polska (TVP), Jacek Kurski, stated that the country would apply to host the event in 2019, and on 10 December 2018, it was confirmed by the EBU that Poland would host the 2019 contest.

Immediately following the final, Kurski stated that Warsaw would not host as it does not have a suitable venue to host an event of this size, marking the first time since the 2014 contest that the event is not hosted in the host country's capital. On 18 January 2019, in an interview for TVP Info, Director-General of the EBU Noel Curran stated that the contest would be held in Kraków, however the same day TVP issued a statement that the city had not yet been chosen. In February 2019 it was revealed that three cities remained in the race: Gliwice, Szczecin and Toruń, and that all of the bids were approved by the EBU, meaning that the final decision regarding the host was exclusively up to the host broadcaster. On 6 March 2019, during a press conference held by TVP and the EBU, it was confirmed that the contest would be held in Gliwice in cooperation with the Silesian Voivodeship.
