Hungu (Korean: 훈구파; Hanja: 勳舊派; RR: hungupa) was a political faction of the Joseon Dynasty in the 15th and 16th centuries.
After the death of Sejo and ascension of Seongjong of Joseon, the rival faction Sarim gained power and influence.
The Hungu retaliated under the reign of Yeonsangun in two violent purges of Sarim members.
After Yeonsangun's overthrow by pro-Sarim Jungjong and his minister Jo Gwang-jo, Hungu engineered a third purge that resulted in Jo's death.
In 1567, with the ascension of Seonjo of Joseon to the throne, the influence of Hungu permanently ended in favor of Sarim.
