The Eurovision Song Contest is an international song competition organised annually by the European Broadcasting Union featuring participants representing primarily European countries. Each participating country submits an original song to be performed on live television and radio, with competing countries then casting votes for the other countries' songs to determine a winner.

The final stages of the 2023 edition of the contest will take place in the United Kingdom in May 2023. Semi-finals will be held on May 9 and 11, and the grand final scheduled to be held on May 13.
