Lambert started nine games for the Cavaliers in 2014, completing 59% of his passes for 1,632 yards, 10 touchdowns and 11 interceptions.
Lambert graduated from Virginia in May and will therefore be eligible to play immediately for Georgia.
Georgia seeks to replace graduated quarterback Hutson Mason, who threw for 2168 in 2014. Lambert joins junior Faton Bauta, sophomore Brice Ramsey and redshirt freshman Jacob Park on the Bulldogs' depth chart.
