Theodore Anthony Nugent (; born December 13, 1948) is an American singer-songwriter, guitarist, and pro-gun political activist. He initially gained fame as the lead guitarist of The Amboy Dukes, a band formed in 1963 that played psychedelic rock and hard rock. After dissolving the band, he embarked on a solo career. Nugent is known for his Gibson Byrdland, his bluesy and frenzied guitar playing and his energetic live shows. Despite possessing a distinctive, wide-ranging singing voice, Nugent recorded and toured with other singers during much of his early solo career, including Derek St. Holmes, Brian Howe, and Meat Loaf, only taking on full lead vocal duties later on. In the late 1980s and early 1990s, he was part of the supergroup Damn Yankees.
In later years, Nugent has drawn attention for his outspoken conservative political views, as well as his strident advocacy of hunting and gun ownership rights. He is a board member of the National Rifle Association and a strong supporter of the Republican Party. He has made a number of controversial and threatening statements against advocates of gun control; in one case, the Secret Service investigated him based on comments about President Barack Obama.
