Jackson was born in Baton Rouge, Louisiana, and raised in Fort Worth, Texas. He played football and basketball at Arlington Heights High School in Fort Worth, graduating in 1968. A severe injury permanently sidelined his football career at the University of Texas without him ever lettering. After graduating from the University of Texas at Austin, Jackson taught social studies at LBJ High School in Austin, Texas.

Jackson started acting in his late 20s, at a community theater. In 1980, Jackson went to New York City, and later to Hollywood, to further his acting career. He had small roles in a number of television and motion picture productions, most notably a recurring role in the series Wiseguy. In 1986, he appeared in the TV film Blind Justice, starring Tim Matheson. In 1987, Jackson had a small role in the MacGyver episode "Birth Day" as LA police sergeant Meechum who recognizes MacGyver's flag help signal, saying he does so because he spent four years in the Navy. In 1992, Jackson played Captain West, a senior JAG officer, in the American drama film A Few Good Men. In 1996, Jackson took on the role of Rear Admiral A. J. Chegwidden (the Judge Advocate General of the Navy) in JAG, which he would continue to play for eight consecutive years. Jackson was Johnny B./Eli Ferguson in The Spitfire Grill. His mother was played by Ellen Burstyn. Jackson had a recurring role as FBI Deputy Director Sam Cullen in the first season of Fox series Bones. Jackson appeared in the series finale of Jericho as the ambassador of Texas to the Allied States of America. Jackson portrayed C-130 pilot Gus in the NBC series Knight Rider and has recently appeared on CSI: Crime Scene Investigation. Jackson returned to the role of retired admiral A.J. Chegwidden, now a civilian lawyer, in the NCIS season 10 finale, broadcast on May 14, 2013 and again as a recurring character on NCIS: Los Angeles in its 8th and 9th seasons.

Jackson is married to Jana Gale Hawkins Jackson. They have a son, former Major League Baseball player Conor Jackson, and a daughter.
