Yima (simplified Chinese: 义马; traditional Chinese: 義馬; pinyin: Yìmǎ) is a county-level city under the administration of Sanmenxia in Henan, China. It is located along the old Xiaohan Route, historically serving as a connection between the important eastern and western capitals of Luoyang and Chang'an.

The area has been a site of military and commercial importance since antiquity. Yima's history dates back more than two thousand years to the Xin'an county of Qin dynasty.

Yima became Henan's first county-level city in 1981, initially managed by the Luoyang Administrative Office and transferred to Sanmenxia in 1986. Today, it is one of Henan Province's 48 counties with extended autonomy. It is the smallest city in China (112 square kilometers with a population of about 140,000).
