Derby manager Nigel Clough and his backroom staff have signed new deals until the summer of 2015.
The 45-year-old's contract was due to expire at the end of the season and he had been linked with a move to local rivals Nottingham Forest.
Clough, who has steered the Rams to fourth spot in the Championship this season, took over at Pride Park in January 2009.
"We believe there are some good times ahead of us," he told the club website.
Chief executive Tom Glick told the club website: "Our commitment to Nigel and his team has been consistent throughout.
"We have always seen the incredible work taking place behind the scenes, with all levels of the club improving under his leadership."
