Z'ha'dum is the final episode of the third season of the science fiction television series Babylon 5.

Aboard Babylon 5, John Sheridan and Delenn are shocked by the appearance of Sheridan's wife, Anna, believing her to have died on the Shadow homeworld, Z'ha'dum. Anna, aware of the conflict with the Shadows, allows herself to be submitted to medical tests to prove her identity, as she wants to have Sheridan return with her to Z'ha'dum. Dr. Franklin verifies she is Anna, but is unable to explain the presence of epidermal scarring. Privately, Delenn tells Sheridan that she knew Anna was still alive, but could not tell Sheridan as he would risk his life to save her; Sheridan doubts if he can trust Delenn again but she admits she still loves him.

Meanwhile, Ivanova prepares the station for potential conflict, and G'Kar offers a supply of thermal fusion weapons stashed aboard the station that can be used to take out Shadow vessels when they come out of hyperspace. Elsewhere, Londo tells Vir that he has been promoted to an adviser of the Centauri Empire, which he considers as punishment to allow his actions to be more closely monitored. A human tells Londo that they share a common friend and that if he values his life, he will leave the station; both Londo and Vir agree this "friend" is Morden, a human working for the Shadows.

Sheridan approaches Anna and tries to learn more, agreeing to go to Z'ha'dum if she explains how she ended up there. Anna recounts that she had been invited by Dr. Chang of Interplanetary Expeditions (IPX) to board the Icarus and study an ancient civilization on a planet near the Rim discovered by one of their probes. She later learned that Dr. Chang lied; IPX had previously discovered an alien ship buried on Mars and activated it. They feared that the owning species would come for it, so they equipped it with a tracking device. As expected, the ship was unearthed days later by an unknown species, and was traced to this planet: Z'ha'dum. There, they traced an energy source to the center of the planet, where they met the Shadows. Though most of the Icarus crew was destroyed by an apparent accident, Anna and the other survivors were offered a chance to stay alive and study the advanced technology in exchange for remaining quiet about their discovery.
