Boer has already gained plaudits for his leadership after standing in for last year's skipper Phil Vickery on several occasions, not least the 'Cherry and Whites' Powergen Cup Final victory against Northampton at Twickenham.
But now the 27-year-old will officially take the title, with Vickery likely to be absent for much of the early part of the season on England duty.
"Jake was very successful as a captain last season, proving he is more than capable to do the job," said Gloucester's Director of Rugby Nigel Melville.
"We needed someone who is going to be with us all season, and Jake will be."
Boer – who also had stints with London Irish and Leicester Tigers – arrived in England back in 1997 and was a key man in Gloucester's dominant form for much of the domestic season.
"It's a great honour first and foremost," Boer told Gloucester's official website.
"I captained the team for a lot of last year and it was a great learning experience for me, but to be announced as club captain is brilliant and I am very proud. I hope I don't let anyone down.
"I like to play my own game and lead by example, hopefully I can lead the guys to achieve even bigger and better things than last year."
Gloucester kick-off their new season with a pre-season friendly against against Glasgow on August 14.
