Paul deParrie (June 19, 1949 – May 20, 2006) was an American pro-life activist and author who lived in Portland, Oregon. He was the executive director of Believers Against Child Killing and editor-in-chief of Life Advocate magazine. He advocated for the use of justifiable homicide against abortion providers, and was a signatory of Paul Jennings Hill's "Defensive Action" manifesto. He was known for his trademark, the black beret. He died from a heart attack after years of heart problems on Saturday, May 20, 2006 at the age of 56. DeParrie was a member of the Constitution Party, but stated that he would leave if the state party would not disaffiliate from the national party. However, deParrie died on the day the steering committee for the Constitution Party of Oregon convened to consider disaffiliation, which it ultimately chose.
deParrie was also a member of Operation Rescue and was arrested several times while protesting.
