Also confirmed for this year's event is a Saturday Night Fever evening, with Kool & the Gang, Chic featuring Nile Rodgers and the Earth Wind & Fire Experience featuring Al McKay.
Organiser Rob da Bank said: "I can't believe it's still only January yet my heads firmly entrenched in a field in Dorset in July thinking about all the mighty musical offerings and other fun and games we have lined up for Camp Bestival.
"From Chic to Hot Chip, Jimmy Cliff to Little Dragon and Mr Tumble to Rizzle Kicks it's another very diverse lineup reflecting all the different ages and tribes that descend on Lulworth Castle each year! I hope to see you there."
