Little Nicholas: Happy As Can Be (French: Le Petit Nicolas : Qu'est-ce qu'on attend pour être heureux ?) is a 2022 French animated comedy film directed by Amandine Fredon and Benjamin Massoubre. The film portrays the story of René Goscinny and Jean-Jacques Sempé as they create the influential Le Petit Nicolas series of illustrated children's books, blending both scenes that directly adapt vignettes from the books and scenes that depict the real world creation of the books including Goscinny and Sempé interacting with and talking to Nicholas directly.

The film stars Alain Chabat as Goscinny, Laurent Lafitte as Sempé, and Simon Faliu as Nicholas. Goscinny's daughter, Anne Goscinny, was one of the writers.

The film premiered as a special screening at the 2022 Cannes Film Festival.
