Old Town Hall Building was the first civic building to house the Colombo Municipal Council.

It is located on Main Street near Gaspaha Junction in Pettah, Colombo.

Constructed in 1873, it served as the meeting place for the Colombo Municipal Council until it moved to the current Town Hall, near Viharamahadevi Park, in 1925.

Today, it houses a small museum featuring various municipal artifacts.
