William Morgan Clark is a fictional character and a major antagonist from the universe of the science fiction television series Babylon 5, portrayed by Gary McGurk. His character rarely appeared on-screen, but is a major off-screen presence in the show.

Clark became president when Earth Force One, carrying President Luis Santiago, was destroyed in 2258. He was complicit with the assassination, in order to take office. He believed Earth to be in danger of being overrun by extraterrestrial races, and so the Nightwatch, a fascist, paramilitary organization, was created to find out people suspected to be alien infiltrators or sympathizers.

EarthForce's Chairman of the Joint Chiefs of Staff, General William Hague, suspected that Clark was involved in the assassination, and began a low-level counter-conspiracy that included Captain John Sheridan. In 2260, John Sheridan and General Hague found evidence that Clark had arranged the assassination of Santiago. Hague managed to get the evidence introduced in the Senate, which caused an uproar.

At about the same time, it was revealed that Clark's forces had found a Shadow vessel buried on Ganymede. Clark was having the ship studied in order to learn its secrets. John Sheridan took the White Star back to Ganymede, and destroyed the vessel. Clark soon issued a decree of martial law using the Ganymede incident as a pretext.

When martial law was declared, Hague began armed resistance against Clark's government. Hague was soon killed in a firefight between his ship, the EAS Alexander and the heavy-cruiser EAS Clarkstown. Meanwhile, Mars rejected martial law, and Clark responded by bombing Mars.
