Wudaokou (Chinese: 五道口; pinyin: Wǔdàokǒu), literally in Chinese the fifth level crossing of the Jingbao Railway, is a neighborhood in the Haidian District of North West Beijing. It is around 10 km from the center of Beijing, between the fourth and fifth ring roads, and has good public transport links including a train station on Line 13 (the CityRail line) of the Beijing Subway. It became a commercial center in Haidian during the 1950s following the establishment of schools. Until as recently as 2001 the area consisted mainly of Hutong neighborhoods and late 1960s apartment blocks, but major development has erased many of these old structures, replacing them with luxury apartments and science parks. Some may also refer to Wudaokou as Koreatown, for its large number of Koreans in the area.

Wudaokou is close to a large number of universities and research institutes, including Beijing Forestry University, Beijing Language and Culture University, Peking University, Tsinghua University, University of Science and Technology Beijing, and China University of Geosciences, and as such has a large student population.
