North Gallia High School was a public high school located near the village of Vinton, Ohio.

It opened in 1965 and closed in 1992 when it was consolidated into River Valley High School.

The North Gallia Local School District was formed in 1965 when the school districts from Bidwell-Porter and Vinton consolidated.

[1] The new district did not immediately consolidate the high schools, so North Gallia High School continued until 1992 with the three others.

At that time, the other high schools were closed and their students were transported to the Kyger Creek High School building, which was renamed River Valley High School.
