RNLI and HM Coastguard volunteers were called out at 9.42pm after a person was spotted in the water near North Pier.
Coastguard rescue officers located the person and guided RNLI crews to them.
Both of the RNLI D-class lifeboats were launched and the person was recovered and brought safely back to shore.
The casualty was then passed into the care of ambulance teams and taken to Blackpool Vic.
