Patrick Joseph Buchanan (; born November 2, 1938) is an American paleoconservative political commentator, author, syndicated columnist, politician, and broadcaster. Buchanan was a senior advisor to U.S. Presidents Richard Nixon, Gerald Ford, and Ronald Reagan, and was an original host on CNN's Crossfire. He sought the Republican presidential nomination in 1992 and 1996. He ran on the Reform Party ticket in the 2000 presidential election.

Buchanan was born in Washington, D.C., a son of William Baldwin Buchanan (Virginia, August 13, 1905 - Washington, D.C., January 1988), a partner in an accounting firm, and his wife Catherine Elizabeth (Crum) Buchanan (Charleroi, Washington County, Pennsylvania, December 23, 1911 - Oakton, Fairfax County, Virginia, September 18, 1995), a nurse and a homemaker. Buchanan had six brothers (Brian, Henry, James, John, Thomas, and William Jr.) and two sisters (Kathleen Theresa and Angela Marie, nicknamed Bay). Bay served as U.S. Treasurer under Ronald Reagan. His father was of Irish, English, and Scottish ancestry, and his mother was of German descent. He had a great-grandfather who fought in the American Civil War in the Confederate army, which is why he is a member of the Sons of Confederate Veterans. He admires Robert E. Lee and the Confederacy. Of his southern ancestry, Buchanan has written: I have family roots in the South, in Mississippi. When the Civil War came, Cyrus Baldwin enlisted and did not survive Vicksburg. William Buchanan of Okolona, who would marry Baldwin's daughter, fought at Atlanta and was captured by General Sherman. William Baldwin Buchanan was the name given to my father and by him to my late brother. As a member of the Sons of Confederate Veterans, I have been to their gatherings. I spoke at the 2001 SCV convention in Lafayette, LA. The Military Order of the Stars and Bars presented me with a battle flag and a wooden canteen like the ones my ancestors carried. Buchanan was born into a Catholic family and attended Catholic schools, including the Jesuit-run Gonzaga College High School. As a student at Georgetown University, he was in ROTC but did not complete the program. He earned his bachelor's degree in American studies from Georgetown, and received his draft notice after he graduated in 1960. The District of Columbia draft board exempted Buchanan from military service because of reactive arthritis, classifying him as 4-F. He received a master's degree in journalism from Columbia University in 1962, writing his thesis on the expanding trade between Canada and Cuba.
