The former Napoli coach has signed a three-year contract.
He said: "I am very happy to be coming to Chelsea and the Premier League. It is an exciting new period in my career.
"I look forward to starting work and meeting the players on Monday ahead of travelling to Australia, where I will be able to get to know the squad and begin our match action.
"I hope we can provide some entertaining football for our fans, and that we will be competing for trophies at the end of the season, which is what this club deserves."
Director Marina Granovskaia added: "We are delighted to welcome Maurizio and are looking forward to him bringing his football philosophy to Chelsea.
