Miyoshi (三芳村, Miyoshi-mura) was a village located in Awa District, Chiba Prefecture, Japan.

The town had a temperate maritime climate with hot, humid summers and mild, cool winters.

The name Miyoshi appears in Nara period records, and is believed to be the location of the original provincial capital of ancient Awa Province.

The area is also part of the setting of the Edo period epic novel Nansō Satomi Hakkenden by Kyokutei Bakin.

On March 20, 2006, Miyoshi, along with the towns of Chikura, Maruyama, Shirahama, Tomiura, Tomiyama and Wada (all from Awa District), was merged to create the city of Minamibōsō.
