A search was launched after a ferry said it had seen a body adrift off the coast of Calais.
Two bodies were subsequently found by a French patrol boat and taken to shore.
Local authorities are investigating the deaths.
A third body was pulled from the Channel near Dover on Tuesday, Kent Police said.
The man’s identity, and whether he was attempting to cross the Channel, are not yet known, and an investigation is under way.
On Wednesday, a body was found on the beach at Calais, according to AFP news agency.
Local maritime officials also reported that two bodies had been found adrift off the city’s coast.
It is not known whether any of these individuals were migrants.
Home Office figures show 263 people crossed the Channel in four boats on Wednesday.
This takes the provisional total for 2024 so far to 31,535.
This is 18% higher than this time last year (26,699) but 21% lower than the same point in 2022 (39,929), a record high year.
Earlier this month, Sir Keir Starmer announced an extra £75m to police the UK’s borders in an effort to reduce the number of small boat crossings.
