"I am delighted to be joining Chelsea at this very exciting time for the club." Chilwell told the club's website.
"I’m looking forward to being a part of this young, dynamic squad led by Frank Lampard as we challenge for honours next season. I can’t wait to get started and hopefully it won’t be long before we’re playing in front of the Chelsea fans at Stamford Bridge."
Club director Marina Granovskaia added: "We are very pleased to have completed our third addition to our exciting squad for the coming season. Ben brings plenty of top-level experience playing in the Premier League, Champions League and at international level, despite his young age.
"We are confident Ben will adapt very quickly to being a Chelsea player and with the fixture programme for 2020/21 especially busy, he is a fantastic addition to the squad needed to challenge for honours."
