The Municipal Offices (Welsh: Swyddfeydd Bwrdeistrefol Blaenafon) are in Lion Street, Blaenavon, Torfaen, Wales.

[1] Following significant population growth, largely associated with the local ironworks, a local board of health was established in Blaenavon in 1858[2] and subsequently established its offices in an existing building in Lion Street;[3] after the area became an urban district in 1894, the new urban district council retained the building as its offices.

[4] By the late 1920s, the building had become dilapidated and council officials decided to demolish the it and to commission bespoke offices on the same site.

The central bay featured a doorway which was flanked by brackets supporting a stone balcony; there were French doors on the first floor and a Dutch gable with finials above.

[11] On completion of the works, the local public library, which had been based in a former school building in Park Street, relocated to the municipal offices.
