厚木市（日语：厚木市／あつぎし）位于日本神奈川县中心的都市，且是一个特例市。

厚木市是根据1986年落实的第4次首都圏基本计划而成立的业务核都市，2002年4月1日升格为特例市。

由于有更早发展的同地名地区，因此大部分以「厚木」为名的公司和组织的总部均不位于本市，造成一些误会。

Atsugi(厚木市,Atsugi-shi) is a city located in central Kanagawa Prefecture, Japan.

As of June 2012, the city has an estimated population of 224,462 and a population density of 2,390 persons per km². The total area is 93.83 km².

While the name “Atsugi” is often associated with the United States Navy base at Naval Air Facility Atsugi, the base is actually not in Atsugi, but straddles the border between the nearby cities of Ayase and Yamato.
