The Eurovision Song Contest 2019 was the 64th edition of the Eurovision Song Contest. It consisted of two semi-finals on 14 and 16 May and a final on 18 May 2019, held at Expo Tel Aviv in Tel Aviv, Israel, and presented by Erez Tal, Assi Azar, Lucy Ayoub, and Bar Refaeli. It was organised by the European Broadcasting Union (EBU) and host broadcaster the Israeli Public Broadcasting Corporation (IPBC/Kan), which staged the event after winning the 2018 contest for Israel with the song "Toy" by Netta.

Broadcasters from forty-one countries participated in the contest, with Bulgaria and Ukraine not returning after their participation in the previous edition. Bulgarian National Television (BNT) cited financial difficulties as the reason for its absence, while the Public Broadcasting Company of Ukraine (UA:PBC), which had originally planned to participate, ultimately withdrew as a result of a controversy surrounding its national selection.

The winner was the Netherlands with the song "Arcade", performed by Duncan Laurence and written by Laurence along with Joel Sjöö, Wouter Hardy and Will Knox. Italy, Russia, Switzerland, and Sweden rounded out the top five; due to a voting error, Norway was originally placed fifth, but placed sixth after a correction. The Netherlands won the combined vote, but placed third in the jury vote after North Macedonia and Sweden, and second in the televote after Norway. Further down the table, North Macedonia and San Marino achieved their best results to date, finishing seventh and 19th respectively.

The EBU reported that the contest had an audience of 182 million viewers in 40 European markets, a decrease of four million viewers from the previous edition. However, an increase of two percent in the 15–24 year old age range was reported. The lead-up to the contest was met with controversy on multiple fronts, primarily on issues surrounding the Israeli–Palestinian conflict, eventually leading to demonstrations by interval act performer Madonna and Icelandic entrants Hatari during the broadcast of the final.

The Israeli Public Broadcasting Corporation (IPBC/Kan) staged the 2019 contest in Tel Aviv, after winning the 2018 contest for Israel with the song "Toy" performed by Netta. It was the third time that the contest was held in Israel, after the 1979 and 1999 contests in Jerusalem. The selected venue was Expo Tel Aviv's 7,300-seat congress and convention centre in "Bitan 2" (Pavilion 2), which was opened in January 2015. Located on Rokach Boulevard in northern Tel Aviv, the convention centre serves as a venue for many events, including concerts, exhibitions, trade fairs, and conferences. The fairground has ten halls and pavilions, plus a large outdoor space. The new pavilion had recently hosted the 2018 European Judo Championships from 26 to 28 April.

After Netta's win in the 2018 contest, both she and the Israeli prime minister Benjamin Netanyahu expressed confidence that the 2019 contest could be held in Jerusalem. Israeli finance minister Moshe Kahlon also said in an interview that the event would be held solely in Jerusalem and estimated its cost at 120 million Israeli new shekels (approximately €29 million). The mayor of Jerusalem, Nir Barkat, mentioned Pais Arena and Teddy Stadium as possible venues to host the event. The municipality of Jerusalem confirmed that because it lacked the seating capacity, the contest would not be held at the International Convention Centre, which had hosted the contest in 1979 and 1999. The event organisers, the European Broadcasting Union (EBU) and incoming host broadcaster Kan, made no comment on the matter.

The EBU had allowed Kan to participate in the 2018 contest without having yet become a full member of the union, while its membership application was being reviewed. On 18 June 2018, Netanyahu stated that the Israeli government had committed to remaining in compliance with EBU rules regarding the constitution of member broadcasters, so as not to affect Kan's right to host the 2019 contest; the broadcaster's establishment included a condition that news programming would be delegated later to a second public broadcasting entity, which would have violated EBU rules requiring member broadcasters to have their own internal news departments. The following day, Kan was officially confirmed as the host broadcaster for 2019, and on 24 June, it formally opened the bidding process for cities interested in hosting the event. Israeli deputy minister Michael Oren stated to Malta's TVM that Jerusalem did not have the resources to host the contest on 28 July, reiterating that Tel Aviv was the more likely host. Oren also indicated that hosting the contest in Tel Aviv would "solve the whole problem"; TVM interpreted this as a nod to the disputed status of Jerusalem, with both Israel and Palestine claiming the city as their capital.

Soon afterwards, reports surfaced of the government not providing the €12 million downpayment requested by Kan to cover hosting expenses and security. Following a tense back-and-forth between Kan and the government, a compromise between the two parties was reached on 29 July 2018 that would see Kan paying the €12 million to the EBU and the Finance Ministry covering expenses should complications arise. The mayor of Tel Aviv, Ron Huldai, stated that the city would be willing to pay for the convention centre itself, should it be chosen as the host city.
