The 6ft 5in keeper has moved to west London in a deal rising to £20million, the PA news agency understands.
He become Lampard’s seventh senior signing of a busy summer following the arrivals of Timo Werner, Hakim Ziyech, Ben Chilwell, Kai Havertz, Thiago Silva and Malang Sarr.
Chelsea director Marina Granovskaia said: “As soon as Petr Cech (technical and performance advisor) and our technical team identified Edouard as the most suitable goalkeeper to complement our existing group, there was only one player we wanted to bring in.
“Edouard arrives following a season of real success with Rennes, he is ambitious for more, and we welcome him to our club.’
