Prusias I Cholus (Greek: Προυσίας ὁ Χωλός "the Lame") (lived c. 243 BC – 182 BC, reigned c. 228 BC – 182 BC) was a king of Bithynia, the son of Ziaelas of Bithynia.

Prusias was a vigorous and energetic leader, he fought a war against Byzantium (220 BC), seizing their Asiatic territory, a part of Mysia that had been in their possession for a long time. then defeated the Galatians that Nicomedes I had invited across the Bosphorus near a territory called Arisba, he then put to death all of their women and children and let his men plunder their baggage.

At some point during his reign, he formed a marriage alliance with Demetrius II of Macedon, receiving the latter's daughter, Apama III, as his wife.

He expanded the territories of Bithynia in a series of wars against Attalus I of Pergamum and Heraclea Pontica on the Black Sea, taking various cities formerly owned by the Heracleans, renaming one them Prusias, after himself. While besieging the city of Heraclea Pontica itself, he dealt many casualties to the besieged, but while climbing a ladder, he was hit with a stone and he broke his leg and the siege was lifted due his injury. This is likely where he was given the surname "the lame" due to his injury.Philip V of Macedon granted him the ports of Keios and Myrleia in 202, which he renamed Prusias and Apameia respectively. Although he granted sanctuary to Hannibal, who fought against the Attalids for him with an odd stratagem but gave him naval success, he remained neutral during the Roman Republic's war with Antiochus III the Great, refusing an alliance with Antiochus. He agreed on peace terms with presumably Eumenes II in 183 BC, in the city of Cyzicus. Apama III bore Prusias I a son called Prusias II, who succeeded him.
