1925 Frankford Yellow Jackets season

The 1925 Frankford Yellow Jackets season was their second in the National Football League. The team improved on their previous output of 11–2–1, winning thirteen league games to finish the season in sixth place. The team's overall record, against league and non-league opponents in 1925 was 15–7.

The team set the record for most games played in a season during the years before the league went to a fixed-length schedule, playing an astonishing 22-game season, including two contests against non-NFL opponents. Three Frankford players (Rae Crowther, Tex Hamer, and Bill Hoffman) played in 19 of 20 regular season league games — a record that still stands.

Even counting playoff games, no NFL team played more than 20 games in a season until the 2021 NFL season when the Cincinnati Bengals and Los Angeles Rams each played 21 games including 17 regular-season games and 4 playoff games on their way to Super Bowl LVI.
