"Long Cool Woman in a Black Dress" (also titled "Long Cool Woman" or "Long Cool Woman (in a Black Dress)") is a song written by Allan Clarke, Roger Cook and Roger Greenaway, and performed by the British rock group the Hollies. In an interview with Johnnie Walker on BBC Radio 2 on Sounds of the 70s in April 2023, Clarke said it had been written by himself and Cook. Cook had a long-standing agreement with Greenaway that any songs written by one of them should be credited to both.
