Natacha is a Belgian comics series, created by François Walthéry and Gos. Drawn by Walthéry, its stories have been written by several authors including Gos, Peyo, Maurice Tillieux, Raoul Cauvin and Marc Wasterlain.
The series tells the adventures of Natacha, a young sexy flight attendant in the service of the flight company Bardaf, and her clumsy, hot-tempered colleague and friend Walter, with occasional participation by her flight captain Turbo and his co-pilot Legrain. Occasionally, the story evolves into Natacha and Walter retelling the adventures of their grandparents, Natacha's museum conservator grandmother (also named Natacha) and Walter's pilot grandfather (also named Walter), in the Roaring Twenties and Thirties.
Natacha was first published in the Franco-Belgian comics magazine Spirou on February 26, 1970. The series eventually ended serial publication in Spirou, leaving its publisher Dupuis, and began publishing albums only through Marsu Productions in 1989, starting with the album Cauchemirage. In 2013, the Marsu Productions was bought up by Dupuis.
In 2025, Natacha was also adapted into a live-action film, Natacha, Hôtesse de l'Air, directed by Noémie Saglio.
