The Man Vs Wild star will follow real life survival stories and demonstrate "dynamic life-saving know-how" along the way.
"I am super excited to be working with Discovery again - the channel where the Man Vs Wild journey began," said Grylls.
"Bear Grylls: Ultimate Survivors, and any future endeavours, will be intense - but that's where the fun is! Man Vs Wild took me to some of the toughest climates and terrains out there, and this new series is an exciting evolution of that."
The show will see the adventurer visit the Amazon, the remote crevasses of the European Alps and the unforgiving North African desert.
Discovery Networks International Exec VP Luis Silberwasser said: "We are thrilled to welcome Bear back to the Discovery fold.
"He is a true game-changer in the survival genre, integral in shaping it into the programming powerhouse that it is today. We are now poised to push the limits even further for our international audience."
Julian Bellamy, creative director and head of production & development at DNI, added: "This show will prove to be a must-see for adventure lovers around the world."
