Own Eurovision Song Contest 51, often referred to as OESC #51, was the 51st edition of Own Eurovision Song Contest. It took place in Gliwice, Poland, following Bovska’s win at the 50th edition in Kazan, Russia with the song “Kaktus”. It was the fifth time that the country hosted the contest, after previously doing so in 13th, 27th, 41st and 45th editions. The contest was held at the Arena Gliwice, and consisted of two semi-finals on 23 January and the final on 30 January 2019. The live shows were hosted by Paulina Sykut-Jezyna.
Forty countries have participated in the competition. The 51st edition saw the return of Bosnia and Herzegovina, Bulgaria, Cyprus, France, Malta, Portugal and San Marino, while Armenia, Azerbaijan, Czech Republic, Faroe Islands, Hungary, Iceland, Latvia, Liechtenstein, Moldova, Monaco, Morocco and Slovenia have decided to withdraw. Despite originally announced their intention to return, Lithuania and Ukraine decided later to not participate.
After a tense voting process, Ireland won the contest for the first time, with Lyra's song "Emerald". This was Ireland's first win – and first top ten placing in the last 32 editions. The margin from the runner-up was 48 points, this being the 3rd biggest margin ever between the top two countries. The podium was completed by Norway and France, with both of them getting their best result since their victories in the 7th and 38th editions respectively. Of the "Big Six", Turkey placed the highest, getting 11th, while Georgia got its worst result ever in the final, finishing last for the second time.
