Cassidy was in hospital with organ failure but died “free from the pain that had gripped him for so long”, his family says.
The singer was rushed to a hospital in Florida last week, with his publicist saying at the weekend that he was suffering organ failure.
He revealed earlier this year he was battling dementia after video emerged of him performing erratically in California.
Cassidy shot to fame in the early 1970s as Keith Partridge in TV sitcom The Partridge Family, starring opposite his real-life stepmother Shirley Jones.
He went on to enjoy a hugely successful pop career and scored two UK number ones with How Can I Be Sure? and Daydreamer.
