The 1956Detroit Lions season was their 27th in the league. The team improved on their previous season's output of 3–9, winning nine games. Despite the improvement, they missed the playoffs for the second consecutive season. Detroit held the top spot in the Western Conference going into the final game of the season versus Chicago, against whom the Lions lost 38-21. Contributing to the loss was Detroit missing quarterback Bobby Layne, who was concussed and removed from the game in the first half due to a unsportsmanlike conduct foul by Ed Matthews, for which Matthews was ejected.
