Goalkeeper Lewis Price and midfielder Lee Hendrie will not be offered new contracts at Derby.
The two players met with boss Nigel Clough this week to discuss their futures following the conclusion of their loan spells at Brentford and Brighton respectively.
Both are out of contract at the end of June and have been told by Clough they will not be offered new deals.
"Lewis and Lee have been to see me and they will be looking for new clubs this summer," Clough told the club`s official website. "Without a doubt we wish both of them well and I am sure they will have no problem in getting fixed up."
Price joined Derby from Ipswich in 2007 and made just nine appearances. He had loans spells at MK Dons and Luton last season and spent the entirety of this campaign on loan at Brentford.
Hendrie arrived from Sheffield United last summer and made 10 appearances before linking up with Brighton in March.
