Hazard said: "I am very pleased to be able to wear the No.10 for Chelsea.
"It is my favourite number and is one I am used to wearing for the national team, as well as the one worn by some of my heroes from when I was a kid, like Zinedine Zidane.
"I hope it brings me a lot of luck in the future and I look forward to the fans seeing me in it next season."
Juan Mata was the previous holder of the shirt before leaving for Manchester United in January.
Hazard has delivered 30 goals and 34 assists since joining Chelsea in the summer of 2012 for £32 million.
