Rodgers earned 48 votes to two for New Orleans quarterback Drew Brees in balloting by a nationwide panel of 50 media members who regularly cover the NFL.
The Packers star is the first Green Bay player honored since Brett Favre concluded a run of three consecutive seasons as MVP in 1997.
Rodgers led the NFL in passing with a 122.5 rating built on 45 touchdown passes, six interceptions and a 68.3 completion percentage as the Packers went 15-1 and won the NFC North.
He joins former Packers Bart Starr, Jim Taylor and Paul Hornung in being selected MVP.
Rodgers is the third consecutive quarterback voted MVP, joining New England's Tom Brady (2007, 2010) and Indianapolis' Peyton Manning (2008,2009).
