Jeonnong-dong () is a dong (neighbourhood) of Dongdaemun District, Seoul, South Korea. It is home to the University of Seoul.
Jeonnong-dong is located behind Cheongnyangni station. It was named Jeonnong-ri because, from the early Joseon period, the area was associated with agriculture, which was highly valued, and it contained the royal agricultural fields known as Jeokjeon (ç±Âç°) or Jeonnong (堸農), directly managed by the king.
In the early Joseon period, Jeonnong-dong belonged to Dongbu Inchangbang of Hanseong-bu. During the Gabo Reform, it was recorded as Dongso-gye Jeonnong-ri in Inchangbang (outside the city) of East and West Hanseong-bu. On April 1, 1911, it was referred to as Jeonnong-ri, Inchang-myeon, Gyeongseong-bu. On April 1, 1914, it was incorporated into Goyang-gun, Gyeonggi-do, as Jeonnong-ri, Sungin-myeon, but on April 1, 1936, with the expansion of Gyeongseong-bu, it became Jeonnong-jeong of Gyeongseong-bu. On April 1, 1943, with the implementation of the district system, it was placed under Dongdaemun-gu.
After Korea's liberation, on October 1, 1946, Japanese-style place names were replaced with Korean names, and it reverted to Jeonnong-dong, which it remains today. In 1955, it was divided into Jeonnong 1-dong and 2-dong. On October 31, 1959, due to administrative changes, Jeonnong 3-dong was split again. On May 18, 1970, Jeonnong 4-dong was separated, and on May 4, 2009, the name of Jeonnong 3-dong was changed to Jeonnong 2-dong.
