Monica Swinn (born Monika Swuine; 19 September 1948) is a Belgian actress, best known for her roles in European softcore erotic films of the 1970s, particularly those of the sexploitation and horror film genres. She acted in 20 of Jesús Franco's films, which occasionally featured her in hardcore lesbian scenes with Lina Romay and another Franco regular, Alice Arno; different versions of films such as Female Vampire (1973) had to be produced because of their explicit scenes.

She tended to play characters with a sexual vulnerability, usually maids, prisoners or isolated aristocratic women, although two of her lead roles were as a sadistic wardress in Franco's women in prison film Barbed Wire Dolls (1976) and as a nightclub singer and Madam for the SS in Alain Payet's Nazisploitation film, Hitler's Last Train (1977). According to Swinn herself she was typecast, recalling after reading a typical Franco script: "I'd mull over the previous scenes and think to myself, "This can't be the same character. How many films am I really making here?".
