Miyagino-ku (宮城野区) is the northeastern ward of the city Sendai, in Miyagi Prefecture, Japan.

Miyagino-ku is located on the coast, bordered by Sendai Bay on the Pacific Ocean to the east, and by the city of Tagajō to the north.

The area of present-day Miyagino-ku was part of ancient Mutsu Province, and has been settled since at least the Japanese Paleolithic period.

The area was inhabited by the Emishi people, and came under the control of the imperial dynasty during the late Nara period from their base at Tagajō.

During the Heian period, the provincial capital of Mutsu Province was located near the vicinity of Iwakiri Station.
