"My Girlfriend's Girlfriend" is a song from American gothic metal band Type O Negative's 1996 album October Rust. The first single off of the aforementioned album, it describes a polyamorous relationship. According to an interview in Livewire, it was written at bandmate Josh Silver's house in a short amount of time. With its prominent organ and the almost lighthearted mood throughout, the song much more closely resembles 1960s psychedelic rock than the doom metal that prevails for most of the album.
