Ivan Ljubicic is a Croatian tennis coach and former tennis player.

He is the son of a Croatian father and a Bosnian mother - the city where he was born in 1979 is currently within the Bosnian borders - but he has acquired Croatian citizenship. 193 cm tall and 92 kg, right-handed, in his career he reached third place in the ATP world rankings. In his career he has won awards for over ten million dollars. From 2016 to 2022 he was Roger Federer's coach.

On April 15, 2012, with the defeat against compatriot Ivan Dodig in the first round of the Monte-Carlo Rolex Masters, he put an end to his racing career. Immediately after retiring he started working in the Italian studios of Sky Sport as a tennis pundit, dealing with the 2012 edition of the Wimbledon tournament.

In 2013, Ljubicic first became the manager of the renowned Czech tennis player Tomas Berdych and then in June the new coach of the powerful Canadian Milos Raonic, who under his guidance gained several positions in the ATP ranking. On December 8, 2015 he was hired as coach by Roger Federer to replace Stefan Edberg. With the management activity he followed the career of other top tennis players, including Matteo Berrettini.

In 2021, he founded the Ljubicic Tennis Academy on the Croatian island of Losinj, with the aim of offering young talents and established tennis players the opportunity to train in a peaceful environment. In his academy he was one of the organizers of the Challenger Losinj Open tournament, which opened in October 2021.
