Seihoku Park Ishinomaki, Public park in Ishinomaki, Japan.

Seihoku Park Ishinomaki is the nickname, used since 30 June 2019 under a naming-rights deal with Seihoku, of the Ishinomaki City General Sports Park in Ishinomaki, Miyagi Prefecture. The municipal park holds the Ishinomaki Civic Baseball Stadium, host of Eastern League professional games and a main venue for prefectural high-school and corporate baseball, plus the Ishinomaki Football Ground, used for Vegalta Sendai mini-camps and several J. Satellite League matches a year, and the Fureai Ground.

The park was transformed following the Great East Japan Earthquake of 2011 and includes memorial elements honoring those affected by the disaster. These commemorative features remain central to the park's landscape and identity.

The park serves as a gathering place where local schools and community organizations hold sports events, festivals, and seasonal celebrations throughout the year. In spring, residents visit to enjoy the flowering cherry trees and spend time together outdoors.

The park is easy to access on foot and offers plenty of space for relaxation and activity for visitors of all ages. It is best to visit during fair weather to fully enjoy the outdoor facilities.

The naming rights were acquired by Seihoku, a company whose name is written セイホク, from 30 June 2019, when the nickname Seihoku Park Ishinomaki came into use. The park itself is owned by Ishinomaki City and run under a designated manager system.
