Tama Hills

is an area of hills stretching across southwest Tokyo and northeast Kanagawa Prefecture in the Kantō Plain on Honshū, Japan. Its total area is approximately 300km2。Tama River marks its northeastern boundary.

It straddles the municipalities of Hachiōji, Hino, Tama, Inagi and Machida cities in Tokyo and Kawasaki and Yokohama cities in Kanagawa.

The area is dotted with remains of Jōmon period hunter-gatherer settlements.

The area had been developed extensively since the 1950s to support demand for housing around rapidly-expanding Tokyo and Yokohama. The hills are now mostly a patchwork of new residential suburbs and low, forested hills and pockets of remaining farmland. Some fairly large areas of forests still exist in places. Most notable among the housing developments are Tama New Town and Kohoku New Town.

Points of interest in Tama Hills include:
* Tama zoo - one of the main zoos in Japan.
* Zoorasia - a new zoo in Asahi ward, Yokohama.
* Yomiuri Land amusement park
* Nihon Minka-en - a collection of 20 traditional Japanese farmhouses in Tama ward, Kawasaki.
