2020 Arizona Cardinals season

The 2020 season was the Arizona Cardinals' 101st in the National Football League (NFL), their 33rd in Arizona and their second under head coach Kliff Kingsbury. It was also the first full season since 1971 without the ownership of Bill Bidwill, who died during the 2019 season.

The team improved on their 5–10–1 record from the previous year beginning the season 6–3; however, despite that and acquiring All-Pro wide receiver DeAndre Hopkins midway through the season, the Cardinals suffered a late season collapse, losing five of their last seven games and missed the playoffs for the fifth consecutive season after losing to the rival Los Angeles Rams in Week 17. The Cardinals finished tied with the Chicago Bears for the last Wild Card spot, but lost the tiebreaker.
