Luka Ivanović (Serbian: Лука Ивановић; born 18 May 1992), professionally known as Luke Black, is a Serbian singer-songwriter. Born in Čačak, he became the first Serbian artist to be signed under Universal Music Group, through which he released his debut EP Thornes in February 2015. It was followed by Neoslavic (2018) and F23.8 (2023). Luke Black is set to represent Serbia in the Eurovision Song Contest 2023 with the song "Samo mi se spava".
Luka Ivanović was born on 18 May 1992 in Čačak, FR Yugoslavia. He pursued interest in music at the age of 12 when he started writing his own lyrics, and a couple of years later also began creating and producing music. After graduating from the Grammar School of Čačak, Ivanović relocated to Belgrade to study English language and literature. He later moved to London, where he eventually graduated with a master's degree in music production.
Ivanović stated that his stage name "Luke" comes from the anglicisation of his first name, while "Black" originates from when he as a teenager expressed forty days of mourning for the "death of the Serbian music scene".
