Iceland participated in the Eurovision Song Contest 2015 with the song "Unbroken" written by Pálmi Ragnar Ásgeirsson, Ásgeir Orri Ásgeirsson, Sæþór Kristjánsson and María Ólafsdóttir. The song was performed by María Ólafs. The Icelandic entry for the 2015 contest in Vienna, Austria was selected through the national final Söngvakeppnin 2015, organised by the Icelandic broadcaster Ríkisútvarpið (RÚV). The selection consisted of two semi-finals and a final, held on 31 January, 7 February and 14 February 2015, respectively. Six songs competed in each semi-final with the top three as selected by a public televote alongside a jury wildcard advancing to the final. In the final, the winner was selected over two rounds of voting: the first involved a 50/50 combination of jury voting and public televoting, which reduced the seven competing entries to two superfinalists and the second round selected the winner exclusively through public televoting. "Unbroken" performed by María Ólafs emerged as the winner after gaining 55.89% of the public vote.

The Eurovision Song Contest 2015 was the 60th edition of the Eurovision Song Contest. It took place in Vienna, Austria, following the country's victory at the 2014 contest with the song "Rise Like a Phoenix" by Conchita Wurst. Organised by the European Broadcasting Union (EBU) and host broadcaster Österreichischer Rundfunk (ORF), the contest was held at the Hall D of the Wiener Stadthalle and consisted of two semi-finals on 19 and 21 May, and a final on 23 May 2015. The three live shows were presented by Austrian television presenters Mirjam Weichselbraun, Alice Tumler and Arabella Kiesbauer, while the previous edition's winner Conchita Wurst acted as the green room host.
