Philip Francis Berrigan (October 5, 1923 – December 6, 2002) was an internationally renowned American peace activist, Christian anarchist and former Roman Catholic priest. Along with his brother Daniel Berrigan, he was for a time on the FBI Ten Most Wanted Fugitives list for acts of vandalism including destruction of government property.

Philip Francis Berrigan was born in Two Harbors, Minnesota, a Midwestern working class town, the younger brother of Daniel Berrigan. Their father, Tom Berrigan, was second-generation Irish-Catholic and proud union man.

In 1943, after a single semester of college, Berrigan was drafted into combat duty in World War II. He served in the artillery during the Battle of the Bulge (1945) and later became a Second Lieutenant in the infantry. He was deeply affected by his exposure to the violence of war and the racism of boot camp in the Deep South. Philip soon entered a Josephite seminary and became active in the Civil Rights movement. He marched for desegregation and participated in sit-ins and bus boycotts. He was ordained in 1955, but left the priesthood 18 years later, in 1973. He would marry late in life to Elizabeth McAlister of Jonah House , in Baltimore, which they founded as a community to support resistance. Their three children--Frida, Jerry, and Kate—all grew up to be anti-war activists.
