"Mercury Poisoning" is a song written by rock musician Graham Parker and performed by Graham Parker and the Rumour. Inspired by Parker's frustration with his record company, Mercury Records, the song was released as a promotional single by Parker's new label, Arista Records, in February 1979. Because of the song's controversial nature, it was pulled from its planned release as the B-side to Parker's 1979 single, "Protection."
