Cooper masterminded a 12-point haul from five games as Swindon became the first side to beat leaders Bristol City.
Town also defeated promotion rivals Preston North End and Peterborough United.
Chris Hughton chairs the Sky Bet Manager of the Month judging panel.
He said: “A great month for Mark Cooper’s men in Sky Bet League 1.
“Although Swindon lost one game their victories against promotion rivals and the quality of opposition they defeated was extremely notable.”
Sky Sports’ Football League pundit Don Goodman said: “A four-game winning streak has brought Cooper’s Swindon side to within touching distance of the Sky Bet League 1 summit.
“Being able to pull his side up after an embarrassing FA Cup defeat showed Cooper’s ability to motivate his squad.”
Sky Bet Football Trading Manager Paul Lowery said: “After a defeat at MK Dons at the start of the month, Cooper’s Swindon rebounded brilliantly, winning all four of their remaining games.
“Cooper has been working on the team defensively as Swindon only conceded three league goals during the month."
In the Sky Bet Championship, Mark Warburton of Brentford was named Sky Bet Manager of the Month.
The Sky Bet League 2 Manager of the Month Award went to Southend United manager Phil Brown.
The judging panel for the Sky Bet Manager of the Month is chaired by former Norwich City & Newcastle United manager Chris Hughton, with Sky Sports’ Football League expert Don Goodman; Football League Chief Operating Officer Andy Williamson; League Managers’ Director Olaf Dixon and Sky Bet Football Trading Manager Paul Lowery.
