List of NFL quarterbacks who have posted a perfect passer rating

In the National Football League (NFL), the highest official passer rating that a quarterback can achieve is 158.3, which is considered a perfect passer rating. To qualify, a quarterback must attempt at least 10 passes, have zero interceptions, and have minimums of a 77.5% completion percentage, 11.88% touchdown passes percentage, and 12.5 yards per attempt. The passer rating was developed in 1971.

Applying the formula to post-1971 quarterbacks, as of November 2015^[update], there have been 54 different players, on 65 occasions, who have achieved a perfect passer rating. Four of these ratings have occurred in the post-season. Seven quarterbacks have achieved the feat more than once: Peyton Manning threw four, Ben Roethlisberger and Kurt Warner have thrown three, and Craig Morton, Dave Krieg, Ken O'Brien, and Tom Brady have two.

Ben Roethlisberger is the only quarterback with multiple perfect ratings in a single regular season, when he achieved the feat twice in 2007. The San Francisco 49ers had two different quarterbacks achieve a perfect rating in the same season, with Steve Young (week 7) and Joe Montana (week 10) both earning perfect ratings.

Drew Bledsoe, Robert Griffin III, and Marcus Mariota are the only quarterbacks to achieve a perfect passer rating in their rookie seasons, with Mariota being the only quarterback to post one in his NFL debut.

Four of these performances were in a losing cause, though Chad Pennington is the only quarterback to play from start to finish and earn both a loss and a perfect rating. Eleven quarterbacks have had a perfect 158.3 passer rating and also earned a 0.0 (lowest) passer rating during their careers: Johnny Unitas, Joe Namath, Terry Bradshaw, Len Dawson, Bob Griese, James Harris, Bob Lee, Craig Morton, Dan Fouts, Eli Manning, and Peyton Manning.
