The 24-year-old centre-back has penned a one-year contract at the Valley after impressing during a trial period.
Manager Chris Powell said: "We're delighted to get Dorian on board and he will enhance our squad.
"He has done very well during his trial period, and we feel he will bring extra quality to our ranks. We're very pleased and look forward to working with him."
Dervitte made just one appearance during four years at Spurs before joining Villarreal.
