This is a list of National Football League quarterbacks who have led the regular season in pass completion percentage each year. 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. Five quarterbacks have led the NFL in completion percentage in four different seasons (Sammy Baugh, Bart Starr, Joe Montana, Steve Young, Drew Brees), and one player (Len Dawson) achieved the same feat in the AFL. Otto Graham led the AAFC in 1947 and the NFL three times (1953-1955).
