Jeong Hyo-hang was an early Joseon scholar-official, a son of Jeong Ji-nyeon and elder brother of Minister of Personnel Jeong Hyo-sang; his dates of birth and death are unknown. He passed the 1451 special civil examination as a licentiate, became vice-lecturer when King Sejo took the throne in 1455 and was enrolled as a second-class original-merit subject.
In 1467 he served as Jipyeong, then Director of the Seonggyungwan, and finally rose to Cheomji jungchubusa. Under Seongjong he joined Seo Geo-jeong and others in compiling the 50-volume Dongguk Yeoji Seungnam, and in 1485 he took part in editing the 57-volume Dongguk Tonggam.
These geography and history works were major state projects of early Joseon, and he is remembered as one of the scholars who worked on them.
It is striking that the brothers Jeong Hyo-hang and Jeong Hyo-sang entered office early under Sejo, whereas their father Jeong Ji-nyeon withdrew home after Danjong was deposed; both sons were enrolled as merit subjects. Later opinions about the family's course may differ, but his scholarly contribution survives in the record of the compilation projects.
His dates of birth and death are not recorded, so his active years can only be gauged from examination and office records. With more than thirty years between the 1451 civil examination and the 1485 editing of the Dongguk Tonggam, he appears to have had a long official career. Descendants, tomb and posthumous title could not be confirmed. For how he connects to the Nosongjeong-gong line of his father, see the branch entry.
His father was Jeong Ji-nyeon and his younger brother Jeong Hyo-sang. His descendants could not be confirmed.
