"I-Feel-Like-I'm-Fixin'-to-Die Rag" is a song by the American psychedelic rock band Country Joe and the Fish, written by Country Joe McDonald, and first released as the opening track on the extended play Rag Baby Talking Issue No. 1, in October 1965. "I-Feel-Like-I'm-Fixin'-to-Die Rag"'s dark humor and satire made it one of the most recognized protest songs against the Vietnam War. Critics cite the composition as a classic of the counterculture era.

Country Joe and the Fish was an American psychedelic rock band formed in Berkeley, California, in 1965. The band was among the influential groups in the San Francisco music scene during the mid- to late 1960s. Much of the band's music was written by founding members Country Joe McDonald and Barry "The Fish" Melton, with lyrics pointedly addressing issues of importance to the counterculture, such as anti-war protests, free love, and recreational drug use. Through a combination of psychedelia and electronic music, the band's sound was marked by innovative guitar melodies and distorted organ-driven instrumentals which were significant to the development of acid rock.
