Jessie W. Armstead (born October 26, 1970 in Dallas, Texas) is a former National Football League linebacker who played for eleven seasons with the New York Giants and the Washington Redskins between 1993 and 2003.

Armstead attended Carter High School in Dallas, Texas, before attending the University of Miami. When Armstead committed to Miami, Jimmy Johnson was the head coach. However, weeks later, Johnson left Miami to take over as the head coach of the Dallas Cowboys. After initial reports that Armstead might seek to be released from his commitment to Miami, since the coach who recruited him to play there had departed, Armstead chose to honor his commitment after Dennis Erickson was named head coach.

A college standout, Armstead's pro prospects were diminished after he tore his anterior cruciate ligament his senior season. As a result, he was not drafted until the 8th round of the 1993 NFL Draft, when he was selected by the New York Giants.

Armstead was a five time Pro Bowler, elected between 1997 and 2001. Armstead had 752 career tackles with forty sacks and 12 interceptions for 175 yards. Following an eight-year career with the Giants, he was signed by the Washington Redskins, where he played for two additional seasons.
