Lakeside High School is located in Saybrook Township, near Ashtabula, Ohio, and is the only high school in the Ashtabula Area City School District.

Formed in 2001, it was a merger of the two high schools which had previously existed in the district, Harbor High School and Ashtabula High School.

For its first few years of operation, ninth-grade students were taught in the old Harbor High School, while 10th-12th grade students attended the old Ashtabula High School.

This new building is the first of a total of seven new campus style school buildings to be erected in the area.
