The Abyssinian Meeting House is a historic church building at 73–75 Newbury Street, in the Munjoy Hill neighborhood of Portland, Maine. Built 1828-1831 by free African Americans, it is Maine's oldest African American church building, and the third oldest in the nation.

Trillium Engineering Group was hired to review the existing conditions and provide Structural Engineering needed to bring the structure to code. Findings determined that the building had a significant amount of water in the basement, a leaky roof, and site plan revisions.
