The number eight took the armband on several occasions last season when Mike Tindall was on international duty, lifting the LV= Cup when Gloucester beat Newcastle in the final.
"To be given the role is a huge honour," said the 27-year-old. "I've been at the club for many years now, and in that time I have played under a number of great leaders.
"And in the history of the club there have been a huge number of illustrious captains. So to join those ranks is an absolute privilege.
"Very few men are handed the privilege of being club captain at a club like Gloucester, and I will give it everything I have to make sure I don't let anyone down."
