Sagami (相模国; -no kuni) was an old province. It occupied most of the area that is today Kanagawa prefecture, but present-day Yokohama and Kawasaki, now part of Kanagawa Prefecture, were not in Sagami. Sagami bordered on Izu, Kai, Musashi and Suruga provinces.
The ancient capital of the province was located near modern Hiratsuka. During the Sengoku period, Sagami's chief castle was at Odawara, although it was generally ruled from its larger neighbor Musashi.
