Madam Pheip is a character from the Flemish comic strip The Adventures of Nero by Marc Sleen.

In "De Terugkeer van Geeraard de Duivel" ("The Return of Geeraard the Devil") (1983) Meneer Pheip arranges Nero to be kidnapped because he is jealous that Madam Pheip often goes on adventure with Nero while he is forced to stay home.

Madam Pheip's most colourful character trait is the fact that she is a woman who smokes pipe.

She only smokes the brand "fleur de matras",[4] but in the stories "Moea-Papoea" (1950), "De Bronnen van Sing Song Li" ("The Sources of Sing Song Li") (1952), "De Matras van Madras" ("The Mattress of Madras") (1967) and "Hannibal" (1977) she smokes more heavy stuff, such as tropical snake root, opium, Indian hemp, ... which causes her to hallucinate.

Madam Pheip advises Nero to start pipe smoking which, according to her, scares the Devil away because it reminds him of Hell.

On the fictitious island Moea-Papoea she adopts Petoetje, a small native boy, as her own child.

She finally finds a husband in the story that follows, "De Zwarte Voeten" ("The Black Feet") (1950), where she meets the mayor of Moerbeke-Waas, who also owns a sugar factory.

[7] In "De Groene Gravin" ("The Green Duchess") (1975) the Pheips finally have a son of their own, Clo-Clo.

In "Mama Kali" (1969) she is changed into an African elephant and in "Allemaal Beestjes" ("All kinds of animals") (1981) into a hare.

She is included along with other Nero characters on a bas-relief in Sint-Niklaas, made by sculptor Paul Dekker in 1988 to commemorate Marc Sleen's induction as an honor citizen of the city.
