Derbyshire have signed former West Indies fast bowler Ravi Rampaul from Surrey on a three-year contract.
The 32-year-old seamer joins the county as a non-overseas player and will be available across all three formats.
Derbyshire cricket advisor Kim Barnett said: "We identified new-ball bowling as an area we wanted to strengthen for 2018 and we're delighted to secure someone of the calibre of Ravi.
"He is highly skilled and vastly experienced, with over 100 internationals under his belt, and he will give us the additional firepower we needed alongside the likes of Hardus Viljoen and Will Davis."
Rampaul, who took 49 wickets in 18 Tests, is looking forward to a new challenge after spending two years with Surrey.
Rampaul said: "I'm grateful to Derbyshire for giving me this opportunity to extend my career in England and play across all forms.
"The club has ambitious plans for the years ahead and I'm excited by what we can achieve."
