1934 Detroit Lions

The 1934 Detroit Lions season was the fifth season in franchise history. It was the first season the team played in Detroit; the franchise had previously played in Portsmouth, Ohio, as the Portsmouth Spartans. They failed to qualify for the playoffs for the second consecutive season.

In a Week 8 contest against the Pittsburgh Pirates, the Lions set a single-game NFL record by rushing for 426 yards as a team in a 40-7 win.
