Ukraine in the Eurovision Song Contest 2018

Ukraine participated in the Eurovision Song Contest 2018 with the song "Under the Ladder" written by Mike Ryals, Kostyantyn Bocharov and Anton Karskyi. The song was performed by Mélovin, which is the artistic name of singer Kostyantyn Bocharov. The Ukrainian broadcaster Public Broadcasting Company of Ukraine (UA:PBC) organised a national final in collaboration with commercial broadcaster STB in order to select the Ukrainian entry for the 2018 contest in Lisbon, Portugal. The national selection consisted of two semi-finals, held on 10 and 17 February 2018, and a final, held on 24 February 2018; nine entries competed in each semi-final with the top three from each semi-final advancing to the final. In the final, "Under the Ladder" performed by Mélovin was selected as the winner following the combination of votes from a three-member jury panel and a public televote.

Ukraine was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 10 May 2018. Performing during the show in position 18, "Under the Ladder" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 12 May. It was later revealed that Ukraine placed sixth out of the 18 participating countries in the semi-final with 179 points. In the final, Ukraine performed in position 1 and placed seventeenth out of the 26 participating countries with 130 points. It is the worst position for Ukraine in a contest where it was not the host country.
