Singapore Sling: The Man Who Loved a Corpse (Greek: Singapore Sling: Ο Άνθρωπος που Αγάπησε ένα Πτώμα, tr. Singapore Sling: O Ánthropos pou Agápise éna Ptóma) is a 1990 Greek black and white horror underground art film directed by Nikos Nikolaidis and regarded as his magnum opus. Considered a difficult film to label while still managing to develop something of a cult following throughout the years nonetheless, it was shot in a bizarre manner somewhat resembling film noir or neo-noir and black comedy as well as the exploitation, thriller, and crime genres mixed with some elements of eroticism and horror with sex being used as a power game and received a theatrical release in Greece on 6 December 1990.

Despite Nikolaidis' career as a film director in his home country which stretches to the early 1960s he was almost entirely unknown outside Greece before the early 1990s and is still less known outside it. It was only with this film, which has immediately achieved cult status, that international fame came to him and it probably still remains the film for which he is best known today, as exemplified by the fact that it was released on DVD by Synapse Films, the only one of Nikolaidis' films to so far receive a home video release in North America. In March 2024, Vinegar Syndrome released the film on Blu-ray. The film was officially selected for screening at the Rimini Film Festival.
