Shimo-kitazawa Station (下北沢駅, Shimo-kitazawa-eki) is an interchange station on the Odakyu Odawara and the Keio Inokashira lines located in Kitazawa, Setagaya, Tokyo, and jointly operated by the private railway operators Odakyu Electric Railway and Keio Corporation.

The station gives its name to the surrounding Shimokitazawa neighborhood in the southern corner of the Kitazawa district, which is a popular area for young people in large numbers.

It includes small independently owned shops, cafes, live music venues and theaters.

After a major station reconstruction project, the Odakyu lines were relocated in March 2013 from their prior surface position to new platforms three stories underground.

The Odakyu station consists of two underground island platforms located on the first and second basement levels, serving two tracks each.
