This is a list of National Football League (NFL) quarterbacks who have led the regular season in pass completion percentage each year.
The National Football League (NFL) did not begin keeping official records until the season. In addition to the overall NFL pass completion percentage leaders, league record books recognize the pass completion percentage leaders of the American Football League (AFL), which operated from 1960 to 1969 before being absorbed into the NFL in 1970. The NFL also recognizes the statistics of the All-America Football Conference, which operated from 1946 to 1949 before three of its teams were merged into the NFL, since 2025.
The record for completion percentage in a season is held by Drew Brees of the New Orleans Saints who completed 74.4% of his passes in 2018. This marked the fourth time Brees set the record, having done so previously in 2009, 2011, and 2017. Sammy Baugh led the league in pass completion percentage eight times, a record that was later tied by Len Dawson, who led the AFL seven times and the NFL once.
