Saul Deeney, Ross Atkins, Michael Hoganson and Conor Doyle have all agreed new contracts at Derby.
The quartet were set to see their existing deals expire at the end of June but they have put pen to paper on one-year extensions.
Left-back Hoganson, 19, and forward Doyle, 21, will remain part of the Rams' Under-21 squad for next season but it is hoped Doyle will also go out on loan to gain first-team experience.
Atkins, 23, is also expected to undertake a loan stint but fellow goalkeeper Deeney, 30, will provide back-up for first-choice stopper Lee Grant when he returns to Pride Park on a free transfer from Burnley in the summer.
