Princess Trulala (German: Prinzessin Trulala) is a 1926 German silent comedy film directed by Erich Schönfelder and Richard Eichberg and starring Lilian Harvey, Dina Gralla and Harry Halm.

The old prince promptly leaves, believing that he has to free Arnulf junior from this improper "woman", this waitress.

But eventually everything dissolves in pleasure, and Prince Arnulf gives his blessing to his son's marriage to that false "waitress", Princess Trulala.

And quite en passé, the old man also finds pleasure in Trulala's sister Hopsassa, whom he finally leads home.

Writing for the Immortal Film Heinrich Fraenkel stated: "For Richard Eichberg, it was agreed that the cinema audience would love nothing more than adventurous princesses who sit on cavalier knees, drink champagne and cause teasing stirs.
