In the National Football League (NFL), the highest official passer rating that a quarterback can achieve is 158.3, which is called a "perfect passer rating". To qualify, during a single game a quarterback must attempt at least 10 passes, have zero interceptions, have a minimum completion percentage of 77.5%, have a minimum of 11.875% of their passes score touchdowns, and have a minimum of 12.5 yards per attempt. The passer rating was developed in 1971.

As of the 2020 NFL season, there have been 64 different players, playing in 78 distinct games, who have achieved a perfect passer rating. Four of these games have occurred in the post-season. Eight quarterbacks have achieved the feat more than once: Ben Roethlisberger and Peyton Manning each have four; Kurt Warner and Tom Brady each have three; and Craig Morton, Dave Krieg, Ken O'Brien, and Lamar Jackson each have two.

Ben Roethlisberger (2007) and Lamar Jackson (2019) are the only quarterbacks with multiple perfect ratings in a single regular season. Three teams have had two different quarterbacks achieve a perfect rating in the same season. The Cleveland Browns were first in 1954, with Otto Graham (week 3) and George Ratterman (week 7). They were followed by Dick Shiner (week 1) and Bob Lee (week 5) of the Atlanta Falcons in 1973, and the San Francisco 49ers with Steve Young (week 7) and Joe Montana (week 10) both earning perfect ratings in 1989. Peyton Manning had one perfect rating in the 2003 regular season and one in the post-season.

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.

Five of these performances were in a losing cause, though Chad Pennington is the only quarterback to play from start to finish and record both a loss and a perfect rating. Fourteen quarterbacks have had a game where they earned a perfect 158.3 passer rating and also a game where they earned a 0.0, the lowest possible passer rating, during their careers: Otto Graham, Johnny Unitas, Joe Namath, Terry Bradshaw, Len Dawson, Bob Griese, James Harris, Bob Lee, Scott Hunter, Craig Morton, Dan Fouts, Vince Evans, Rich Gannon, Eli Manning, Peyton Manning, and Geno Smith. Geno Smith had a perfect rating and the lowest possible rating in the same season (2014).

Statistics
Only Nick Foles has accomplished a perfect passer rating with seven touchdowns thrown. Two quarterbacks have accomplished a perfect passer rating with six touchdowns thrown: Peyton Manning was the first to achieve the record on September 28, 2003, against the New Orleans Saints, while Tom Brady matched the feat on October 21, 2007, against the Miami Dolphins. Thirteen quarterbacks have accomplished a perfect game with only two touchdowns thrown: it is impossible to achieve a perfect game with only one touchdown because of the 10 pass attempts minimum to qualify and with the minimum 11.875% touchdown-to-attempted-pass ratio.

Only six quarterbacks have accomplished a perfect passer rating with 30 or more attempts: Ken O'Brien threw 26-for-32 in his perfect game for a completion rate of 81.3%, while Kurt Warner threw 24 of 30 in the second of his three perfect games for a completion rate of 80%, Jared Goff threw 26 of 33 in his perfect game for a completion rate of 78.8%, Dak Prescott threw 25 of 32 for a completion rate of 78.1%, Deshaun Watson threw 28 of 33 for a completion rate of 84.8%, while Aaron Rodgers threw 25 of 31 for a completion percentage of 80.6%. 

Ryan Tannehill holds the record for highest completion rate in a perfect game, throwing 18 of 19 for 94.7% in 2015. Chris Chandler has the best rate for a game with at least 20 pass attempts (23 of 26) for an 88.5% completion rate in his 1995 perfect game.
