The Public Office was a municipal building on Moor Street in Birmingham, England, built between 1805 and 1807.

It was the first important administrative building in Birmingham, and remained the principal local government centre until the 1880s, when the much larger Council House was constructed.

[1] The Public Office was built to give the Birmingham Street Commissioners a permanent headquarters.

The design was described as 'imposing' consisting of a rusticated base, above which was the principal story of six bays, divided by paired Ionic columns which supported an entablature and a balustraded parapet.

[6][4] The building continued to be used by the Birmingham City Police, but in 1909 the Great Western Railway opened Moor Street railway station adjacent to it,[8] and in July that year they purchased the old Public Office from the council for £15,250 (equivalent to £2,010,000 in 2023),[3] in order to demolish it to make way for a new goods station.
