Larry Peccatiello (born December 21, 1935) is a former American football coach. He was an assistant coach with the Washington Redskins from 1981 to 1993. For most of that time, he was defensive coordinator, either alone or sharing it with Richie Petitbon. He was Petitbon's defensive coordinator during his lone season as head coach in 1993.
After Petitbon was fired after the 1993 season, incoming coach Norv Turner jettisoned the remaining staff. From 1994 to 1996, he was defensive coordinator for the Cincinnati Bengals under head coach Dave Shula. When Shula was fired following the 1996 season, incoming coach Bruce Coslet jettisoned the remaining staff.
From 1997 to 2001, he served in the same role for the Detroit Lions, after which he retired. He was first hired by Lions head coach Bobby Ross, and also served under Gary Moeller when Ross resigned during the 2000 season.
One achievement Peccatiello is particularly proud of was his 1983 season with Washington, where he led the defense to 61 takeaways.
Peccatiello earned three Super Bowl rings during his time with the Redskins. In 2010, Peccatiello was inducted into the Virginia Sports Hall of Fame. Additionally, Peccatiello has been inducted to the Newark, New Jersey Hall of Fame, as well as the William & Mary Hall of Fame.
