Nadav Guedj is an Israeli singer born in Paris, France. In 2015, he won the second season of the talent show HaKokhav HaBa (the Israeli version of Rising Star).
The win earned him the right to represent Israel at the Eurovision Song Contest 2015 in Vienna, where he performed the song Golden Boy. The song and his performance became an instant fan favorite, and he gave Israel its first qualification to the final since 2010. He finished in 9th place overall in the grand final.
Nadav was the youngest male artist at that year's contest, and the second-youngest overall (Anita Simoncini of San Marino was several months younger).
