Martin Anthony Lunde (born September 20, 1958), better known by his ring name Arn Anderson, is an American professional wrestling road agent, author, and retired professional wrestler. Although he is widely regarded as one of the greatest tag team wrestlers in history, he also had a successful singles career and became a four-time NWA/WCW World Television Champion, which he often called his "world title".

Anderson's career was highlighted by his alliances with Ric Flair and various members of the wrestling stable The Four Horsemen in the National Wrestling Alliance (NWA) and World Championship Wrestling (WCW). After his retirement, he worked as a producer for WWE until 2019, when he joined All Elite Wrestling (AEW). On March 31, 2012, Anderson was inducted into the WWE Hall of Fame as a member of the Four Horsemen. His son, Brock Anderson also pursued a career in professional wrestling.
