The Scottish international has moved to Pride Park following injuries to Youl Mawene and Dave Walton and is in the squad for the opening day clash against Stoke City.
Caldwell spent last season on loan in the First Division with Coventry City and impressed Rams boss George Burley with his displays.
Burley was keen to bring in defensive cover and feels the 21-year-old will play a key role during his stint in the East Midlands.
"Gary is a young player who I saw play when he was on loan at Coventry last year," Burley told the club's official website.
"He can play at full back or centre back and in view of Mawene and Walton being out through injury it was important we tried to strengthen in defence.
"Gary played in the First Division all last season so he knows what it's about and he was very keen to come here."
