Turner, 29, has signed a four-year contract at the City Ground in a deal which could be worth up to £10million.
With Arsenal closing in on the signing of David Raya from Brentford, Turner would have seen his first-team opportunities limited further if he stayed on in north London.
"It is a great challenge and a great step in my career," said Turner, who moved from the New England Revolution to Arsenal last June and played in their Europa League campaign.
"The manager and the backroom staff, everything about the club has a little sparkle to it. It has felt right from the start and I am happy its got done."
