Luis Reece, George Edwards and Gavin Griffiths will all be released by Lancashire at the end of their current deals.
Batsman Reece (pictured), 25, and 22-year-old bowler Griffiths both progress through the age grades with the latter currently on loan at Hampshire.
Edwards, 24, is a fast bowler who moved to Lancashire from Surrey last year, but he is yet to feature in the County Championship with his only appearance coming in the T20 Blast.
Lancashire head coach Ashley Giles said: “They’re always the hardest decisions but they are not decisions taken lightly. It is something we discuss for a long time but if we feel those players aren’t really in our plans going forward, then it would be wrong to keep them at the club.
“That’s part of my job and it’s a decision not just taken by me, but something that I speak to my coaching team about.
“It’s hard for those guys and we wish them all the best. It’s certainly not something I enjoy and these three guys have been a part of Lancashire’s history. Edwards and Griffiths played at Finals Day last year.”
