Nowon District (Nowon-gu) is a residential district of Seoul, South Korea, located in the most northeastern part of the metropolitan city. It has the highest population density in Seoul, with 619,509 people living in the area of 35.44 km².

Nowon District was formed in 1988 by splitting from Dobong District. The sixteen administrative neighborhoods comprising Dobong-dong, Chang-dong, Wolgye-dong, Gongneung-dong, Hagye-dong, Junggye-dong, and Sanggye-dong became a part of the new Nowon District. The following year, Dobong-dong and Chang-dong were returned to Dobong District.^[2]

Nowon District (and Seoul) is bordered by the mountains Suraksan and Bukhansan, on the northeast. The Jungnangcheon (or Jungnang Stream) flows through the western part of Nowon.

The Gyeongchun and Gyeongwon Lines of Korean National Railroad and the Seoul Metropolitan Subway lines four, six, and seven pass through Nowon District.

Nowon District is home to numerous educational institutes such as Kwangwoon University, Sahmyook University, the Korea Military Academy, Sejong Science High School, Seoul National University of Science and Technology, Induk University, and Seoul Women's University. The large number of schools, universities, and hagwon have given the "gu" the reputation of being the so-called "educational district" of northern Seoul, just like Gangnam and Seocho Districts of southern Seoul.

Kim Seong-hwan of the Democratic Party had been the mayor of the district from July 2010 to February 2018, when Kim resigned to run for the by-election of a National Assembly seat held in the district, which was vacated by Ahn Cheol-soo’s resignation. Kim’s bid was successful and the mayoral office is succeeded to Oh Seung-rok, also a member of Democratic Party.

In April 2013, multiplex cinema CGV Junggye opened in Junggye-dong.^[3]
