Sweden has participated in the Eurovision Song Contest 62 times since making its debut in 1958, missing only three contests since then. Since 1959, the Swedish entry has been chosen through an annual televised competition, known since 1967 as Melodifestivalen. At the 1997 contest, Sweden was one of the first five countries to adopt televoting. Sweden has hosted the contest six times: three times in Stockholm, twice in Malmö and once in Gothenburg (1985); and is set to host for a seventh time in 2024 in Malmö.

The Eurovision Song Contest, often known simply as Eurovision or by its initialism ESC, is an international song competition organised annually by the European Broadcasting Union. Each participating country submits an original song to be performed live and transmitted to national broadcasters via the Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine a winner.
