Mollenard is a 1938 French drama film directed by Robert Siodmak and starring Harry Baur, Gabrielle Dorziat and Pierre Renoir. It was also known by the alternative titles of Hatred and Capitaine Corsaire. The film's sets were designed by Alexandre Trauner. It is based on the novel of the same name by the Belgian writer Oscar-Paul Gilbert. The film's plot divides sharply into halves, with the first an action thriller set in China while the second is a social drama with the title character struggling to cope with what he regards as the suffocating atmosphere of his home port in France.

Robert Siodmak was a German film director who also worked in the United States. He is best remembered as a thriller specialist and for a series of films noir he made in the 1940s, such as The Killers (1946).
