A decorrer desde 1956, o Festival Eurovisão da Canção (em inglês: Eurovision Song Contest, também utilizado no Brasil, e em francês: Concours Eurovision de la Chanson) é um concurso anual de canções transmitido pela televisão com participantes de diversos países cuja televisão nacional transmissora é membro do European Broadcasting Union. O concurso é transmitido na televisão e também na rádio por toda a Europa. Recentemente, a transmissão do mesmo foi também alargada a outros países não europeus por meio dos canais internacionais dos seus membros e também pode ser acompanhada na Internet.

The Eurovision Song Contest, sometimes popularly called Eurovision but not to be confused with the Eurovision network that broadcasts it, is the longest-running annual international TV song competition, held, primarily, among the member countries of the European Broadcasting Union (EBU) since 1956. The competition was based upon the existing Sanremo Music Festival held in Italy since 1951.

Each participating country submits an original song to be performed on live television and radio and then casts votes for the other countries' songs to determine the most popular song in the competition. The contest has been broadcast every year for sixty-two years, since its inauguration in 1956, and is one of the longest-running television programmes in the world. It is also one of the most watched non-sporting events in the world, with audience figures having been quoted in recent years as anything between 100 million and 600 million internationally. Eurovision has also been broadcast outside Europe to several countries that do not compete, such as the United States, Canada, New Zealand, and China. An exception was made in 2015, when Australia was allowed to compete as a guest entrant as part of the celebration of the 60th anniversary of the event. In November 2015, the EBU announced that Australia was invited back as a participant in the 2016 contest after their success in 2015. Following their success again in 2016, Australia competed again in 2017. Since 2000, the contest has also been broadcast over the Internet via the Eurovision website.
