Four years on the fans favourite returns to the helm under the chairmanship of Tony Stewart and replaces the outgoing Mark Robins after he left for Barnsley after two and a half years in charge.
Robins led the club to comfortable safety last season in League Two, overturning a 17 point deduction and working through two administrations during his tenure at Millmoor and then the clubs current home, Don Valley Stadium.
Further details on Moore's appointment will be released in a press conference at 10.30am on Friday morning.
