The Keihin region (京浜地方, Keihin Chihō) consists of the Japanese cities Tokyo, Kawasaki, and Yokohama. The term is mostly used to describe these cities as one industrial region. Keihin is derived from the second character of Tōkyō, 京, which can be read kyō or kei, and the second character of Yokohama, 浜, which can be read hin or hama.

The Keihin region is part of the larger Kantō region.
