Group B winners Nottinghamshire will host local rivals Derbyshire in the quarter-finals of the One-Day Cup.
Notts won the 40-over competition last year and will face their East Midlands rivals on 26 August (14:00 BST).
County Championship leaders Yorkshire, winners of Group A, will entertain Durham on 28 August (10:30 BST).
Essex against Warwickshire will take place the same day with a 14:00 BST start, while Gloucestershire will travel to Kent a day later (14:00 BST).
Warwickshire's meeting with Essex means a quick return trip to Chelmsford for the Bears, who pulled off a 19-run quarter-final victory there in the T20 Blast earlier this month.
