The Ravens (10-5) led 24-7 at halftime and cruised to the finish behind a short-handed defense that harassed quarterback Eli Manning and limited New York (8-7) to 186 yards.
Playing its second game with Jim Caldwell as offensive coordinator, Baltimore scored touchdowns on its first two possessions and amassed a season-high 533 yards — including 289 in the first half alone.
The victory ended a three-game skid for the Ravens and assured them of a home playoff game in the first weekend of January.
The defeat eliminated the defending Super Bowl champion Giants (8-7) from contention in the NFC East and severely damaged their chances of qualifying for a playoff berth.
New York has lost five of seven and was coming off a 34-0 defeat at Atlanta.
