Mike Westhoff (born January 10, 1948) is an American former professional football coach who spent a total of 33 seasons coaching in the National Football League (NFL). He primarily coached special teams for a number of teams, most notably for the New York Jets, Miami Dolphins, and New Orleans Saints. In 2024, he stepped down from his position as assistant head coach for the Denver Broncos due to health reasons. Westhoff is considered to be among the greatest special teams coaches in league history.

Westhoff was the special teams and tight ends coach for the Miami Dolphins from 1986 to 2000.

Westhoff joined the Jets staff in 2001.

He stepped down as the special teams coach for the New York Jets in December 2007 after the final game. On September 1, 2008, it was announced Westhoff would return to the Jets' sideline for the 2008 season in an undefined role.

On August 8, 2010, Westhoff received a one-year contract extension. Westhoff remained with the team through 2011, which he announced would likely be his final year with the team. However, on January 26, 2012, the Jets announced that they had given Westhoff a contract extension through the 2012 season. Westhoff officially retired after the 2012 season.

On November 15, 2017, the New Orleans Saints had hired Westhoff to join their special teams coaching staff for the remainder of the 2017 season. The next day, Saints head coach Sean Payton said that Westhoff would be responsible for supervising all the special teams units.

Following the controversial loss in the 2018 NFC Championship game versus the Los Angeles Rams, Westoff appeared on Mike's On radio show with Mike Francesa of WFAN. On the program, he declared the result of that game as "the toughest loss of his long career".

Westhoff was hired to be the assistant head coach of the Denver Broncos under new head coach, Sean Payton, on February 25, 2023.
