Kean signed a five-year contract with the Premier League club which will pay Juve an initial fee of €27.5million.
The 19-year-old scored six goals in 13 league appearances last season, helping the club secure an eighth consecutive Serie A title.
“I am very proud and honoured to wear the Everton shirt. I will give my best to this team.
“I was convinced to sign because Everton is a club looking to the future and so am I. I know about the size of the club. It has big ambition and I will work very hard to help us fulfil what we want to achieve.
“I am used to winning and I want to bring this winning attitude to the team. I hope I will be very good on the field and bring the fans joy,” Kean told Everton’s official website.
He becomes Everton’s fifth signing of the summer after midfielders Andre Gomes, Fabian Delph and Jean-Philippe Gbamin, and Goalkeeper Jonas Lossl.
