Michael Klinger hopes to help develop the club's younger players during his time as Gloucestershire captain.
The 32-year-old Australian batsman has been signed as the club's overseas player and will be available in all formats of the game this summer.
"It will be a great challenge to captain such a young side," Klinger told BBC Points West.
"Hopefully, I can help some of the younger kids improve and take the next step in their games."
Klinger has had spells with state sides Victoria and South Australia, where he was skipper, and has also appeared for the Australia A team.
Klinger has scored nearly 6,000 first-class runs at an average of 36, and averages 41 in List A cricket and 28 in Twenty20.
He also has previous experience in county cricket, having stood in for
compatriot Phil Hughes as Worcestershire's overseas player
for part of last season, scoring 293 runs in six first-class matches.
"I've been looking to play a full season of county cricket for a few seasons now," he added. "I had a good time captaining South Australia and I can't wait for this opportunity."
Klinger has taken over the captaincy at Nevil Road from Alex Gidman, who
stepped down at the end of the 2012 campaign.
Gloucestershire have been
working on their ground redevelopment
for the last six years, and the costs involved have meant their playing budget has been restricted.
Consequently, the club have had to rely on the younger members of their squad, but director of cricket John Bracewell believes the arrival of Klinger will have a positive effect.
"Michael has vast experience in all formats of the game," he said.
"Right across the board he will be able to help our younger guys with their game management."
