John A. Peavey (born June 6, 1963) is a former American football player and coach.
Peavey played professionally in the National Football League (NFL) with the New England Patriots and the Denver Broncos.
In four seasons as the head coach at Bishop Feehan High School in Attleboro, Peavey led the Shamrocks to four state championship title games and won three of them in a row.
A highlight during this otherwise unsuccessful campaign was leading the Pioneers to their first road win in 25 games and their first home victory in three years.
Peavey's only other collegiate head coaching job was at Southwest Baptist University, where he spent the 2005 and 2006 seasons.
