Patrick W. Castagno is an American track and field coach. He has served as the track and field and cross country coach at the Tatnall School in Wilmington, Delaware, since 2001. Castagno has led Tatnall to over 60 team state championships and over 270 state championships in individual and relay events. In 2026, he was inducted into the Delaware Sports Museum and Hall of Fame.

Biography Castagno attended Salesianum School and later the University of Delaware, competing for both schools in long-distance running. At Salesianum, he was coached by the Reverend Joseph Beattie, an inductee to the Delaware Sports Museum and Hall of Fame, whose ideas influenced Castagno's future coaching philosophy. At the University of Delaware, Castagno competed for the cross country and track teams from 1983 to 1988 under coach Jim Fischer.

In 2001, Castagno was hired by the Tatnall School as a teacher. Across his tenure of over two decades, he turned Tatnall, a small school, into "a cross country and track and field powerhouse", according to The News Journal. He led Tatnall teams to numerous state championships along with top performances at many regional and national tournaments as well. He holds the all-time state record for outdoor track championships as a coach.

Castagno has coached five athletes and eight teams to appearances at the Nike Cross Nationals, and a Tatnall girls distance medley relay team won the 2012 Penn Relays with a time that broke the event record and stood for more than a decade. He also coached three teams to national championships in the 4 × mile relay.
