Joseph Allen "Country Joe" McDonald (January 1, 1942 – March 7, 2026) was an American singer, songwriter, musician and film composer, who was the lead singer and co-founder of the 1960s psychedelic folk-rock group Country Joe and the Fish. He wrote some of the group's most well-known songs, including "Not So Sweet Martha Lorraine" and "I-Feel-Like-I'm-Fixin'-to-Die Rag", the latter a protest song against US involvement in the Vietnam War.
After the group's breakup in 1971, McDonald performed as a solo artist and in the spirit of Woody Guthrie, continued to musically espouse his political views through his original songs.
