Dangerous Acquaintances is the eighth studio album by English singer Marianne Faithfull. It was released on 1 September 1981 by Island Records. The album was seen by reviewers as a disappointing follow-up to Faithfull's Broken English, as the album trades the angry and controversial alternative new wave arrangements of the previous one for a more mainstream rock texture, using over a dozen session musicians and, for some, giving a certain anonymous feel to the songs. The title is a reference to the Pierre Choderlos de Laclos 1782 novel Les Liaisons dangereuses.
