Old East Boston High School (also known as Joseph H. Barnes School) is an historic school building at 127 Marion Street in East Boston, Massachusetts. It now acts as Section 8 housing for elderly or disabled people.

This building is currently under consideration for Boston Landmark status by the Boston Landmarks Commission.

The Renaissance style school was built in 1901 to a design by John Lyman Faxon and expanded in 1933 to a design by Charles R. Greco. It is a three-story structure, faced in yellow brick and limestone, with a flat roof and a raised basement. It is roughly in the shape of an H, with a central section that has side wings projecting to both the front and rear. A circular auditorium section stands behind the central section.

The building was added to the National Register of Historic Places in 2006.
