"Is There in Truth No Beauty?" is the fifth episode of the third season of the American science fiction television series Star Trek. Written by Jean Lisette Aroeste and directed by Ralph Senensky, it was first broadcast on October 18, 1968.
In the episode, the Enterprise travels with an alien ambassador whose appearance induces madness.
This episode was the second appearance of Diana Muldaur in the Star Trek franchise. She appeared previously as Dr. Ann Mulhall in the second season episode, "Return to Tomorrow" and would later appear as Dr. Katherine Pulaski in the second season of Star Trek: The Next Generation.
A Medusan named Zero would later appear as a main character in Star Trek: Prodigy. The name of the season 2 episode "Is There in Beauty No Truth?," which focused on Zero, was a homage to this episode.
