The Northern Ireland international will link up with former Robins manager Steve Cotterill at Turf Moor after signing a three-year contract.
Duff was entering the final year of his deal with Cheltenham and the League Two outfit have decided to cash in now, rather than lose the stopper for nothing.
Though The Clarets have shelled out an initial £30,000 for the centre half, there is also a 15 percent sell-on clause in the deal, in addition to a pre-season friendly between the teams next summer.
Cheltenham chairman Paul Baker admits he had little option but to accept Burnley boss Cotterill's bid due to Duff's contractual situation.
"The club is extremely reluctant to part with Michael but he desperately wanted the opportunity to play at a higher level after nearly eight years with Cheltenham Town," Baker told the club's official website.
"Michael had only one year left on his contract and following discussions with him, it became clear that he could easily walk away for nothing at the end of the season."
