Supported by South Kesteven District Council, the 2021 festival is scheduled for Wednesday 28 April to Sunday 2 May.
Councillor Rosemary Trollope-Bellew, SKDC Cabinet Member for Culture and Visitor Economy, said: "The Deepings Literary Festival has quickly established itself as a major addition to South Kesteven's festival events.
"It is important to acknowledge the hard work and commitment of the local volunteer committee who, in spite of current challenges, have kept together and displayed a positive approach to the planning process for another successful event in 2021."
The current line-up includes Pam Rhodes, Milly Johnson and Ian Macmillan, William Shaw, Frances Pryor, Robert MacMillan and Dorothy Koomson, the best-selling author of My Best Friend's Girl, The Ice Cream Girls and The Brighton Mermaid.
The festival is traditionally held at venues across the Deepings, but 2021's line-up will also include an online contingency programme that will respond to any relevant restrictions still in place at the time of the event itself.
Festival Committee Chair, Cllr Judy Stevens, said: "The Deepings Literary Festival is a favourite with visiting authors, not least for the welcome they receive from residents and visitors from further afield, but also for the intimacy and personal contact with their readers.
"Whilst we hope to run the 2021 event as normal, we will also provide a digital offer. This will extend our audience base and ensure the event goes on."
In the interim, a fantastic digital programme entitled Three Nights in November will be presented across three weekends to promote next year's festival schedule.
The series, hosted on Zoom, will begin with Louise Doughty (14 November), followed by Alison Bruce (21 November) and conclude with Deepings Literary Festival Patron, Elly Griffiths (28 November). All events start at 6.30pm.
