Keane, Rag 'n' Bone Man and Jess Glynne were due to perform at the Staffordshire beauty spot this summer as part of the annual series of concerts organised by Forestry England.
The events will now take place over four successive days in June 2022, with all headline acts due to return.
Jess Glynne will perform on Thursday, June 9, Rag 'n' Bone Man on the Friday and Keane on the Saturday. An artist to perform on the Sunday has yet to be announced.
Tickets already bought for this year's concerts will remain valid for next year, organisers said.
A spokesman for Forestry England said: "The Government’s roadmap out of lockdown has made it clear that we cannot hold our Forest Live concerts this summer.
"We are extremely disappointed, but this is the best way to keep our valued customers safe, as well as the staff, volunteers, contractors and artists that make Forest Live possible.
"We look forward to welcoming Forest Live fans to see their favourite artists performing in the nation’s forests next year.
"We are delighted to confirm that all Forest Live 2021 headline acts have been able to reschedule all their performances and will be joining us in June 2022.
"All bookings remain valid for the 2022 dates and customers will be contacted by their point of purchase. Thank you for your patience and understanding."
The statement added: "We would like to send our deepest apologies to everyone who was hoping to come to a Forest Live gig this summer.
"We can’t wait to experience the best live music in our beautiful forests with you next year and thank you very much for your continued support.”
The Forest Live concert series was also cancelled last year when Will Young, James Morrison and Noel Gallagher's High Flying Birds were among planned performers.
