Spider Jerusalem is a fictional character and the protagonist of the comic book Transmetropolitan, created by writer Warren Ellis and artist Darick Robertson, introduced under the now-defunct Helix imprint of DC Comics before being moved to the Vertigo imprint.

Spider is a renegade gonzo journalist forced to return to The City after having exhausted a substantial advance from a publisher without completing the books required by contract. After five years of effective retirement as a long-haired hermit in a compound in the mountains, he returns to The City to complete the books, takes up work for an urban newspaper to support his writing, and finds himself battling political corruption at the highest level.
