Ramadan ibn Alauddin was a Yuan darughachi (governor) of Luchuan Prefecture in Rongzhou, Guangxi Province, of Muslim faith and Korean provenance. He served until his death in 1349. His existence is known only from an epitaph in the cemetery of the Huaisheng Mosque in Guangzhou. Ramadan is notable for being the first named Muslim from Korea, although it is unclear whether he was of Korean ethnicity.
