Estonia participated in the Eurovision Song Contest 2023 in Liverpool, United Kingdom, with "Bridges" performed by Alika.

Performing during the show in position 4, "Bridges" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 13 May.

The competition consisted of twenty entries competing in two semi-finals on 12 and 14 January 2023 leading to a twelve-song final on 11 February 2023.

A further round of public televoting was held following the semi-finals which determined two wildcards out of the remaining non-qualifying acts to complete the twelve song lineup in the final.

On 31 January 2023, an allocation draw was held, which placed each country into one of the two semi-finals, and determined which half of the show they would perform in.

This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.

The individual rankings of each jury member in an anonymised form as well as the nation's televoting results were released shortly after the grand final.
