Choe U (; 1166 - 10 December 1249) was the second Choe dictator of the Ubong Choe Military regime. He himself went out on the battlefield to lead in fighting off the Mongolian invasions. Then he realized that the government was no longer safe at the capital city of Kaesong, and so he forced the king and his officials to flee to Ganghwa island. He took some of his armies and went to Ganghwa island with them. He did this because he knew that the Mongols would not attempt a naval assault against Ganghwa. Therefore, the Goryeo government was kept safe for several decades even after the Choe regime.
