The popular four-piece will perform a classic blend of 60s, 80s, 90s and current top hits as well as some Italian favourites.
The band features Nerida Griffiths, Tony Bandera, Robbie Murie and Joe Zappia.
Festival Co-ordinator Monique Warnock said The Times was sure to be a great hit with the crowds.
“We’ve had some great acts over the festival’s 14 year history and we are delighted to have The Times headlining next year’s Harvey Harvest Festival on Sunday March 17.
“Nerida Griffiths is a classically trained opera singer and is just amazing to listen to – The Times will be a real treat for all festival-goers.”
