Luka is the Croatian, Serbian, Slovenian and Hungarian form of Luke, going back through Latin Lucas to the Greek Loukas. Standard name dictionaries explain the root as “man from Lucania,” the ancient region of southern Italy. The meaning “bringer of light,” from the Latin lux, is often attached to the name, but it is a popular association rather than the accepted etymology. The name is also the form used for Luke the Evangelist in these languages.
It is pronounced LOO-kah in Italian and LOO-kə in English.
The best-known namesakes are athletes. Luka Modrić, the Croatian midfielder and national team captain, won the Ballon d'Or in 2018 after leading Croatia to the World Cup final. Luka Dončić, the Slovenian guard, has been a five-time NBA All-Star and is regularly described as one of the finest players to come out of Europe.
In the United States the name was rare for decades: in 1975 it was given to six boys and ranked 4,797th. It has risen steeply since, from 707 boys and 439th place in 2017 to 3,873 boys and 85th place in 2025. It first reached the top 100 in 2023, at 95th, and has climbed slightly in each year since.
