Naas Town Hall, Town hall in Naas, Ireland.

Naas Town Hall is a stone building on Main Street North, completed in 1796 as a gaol and re-faced in the Italianate style in the early 20th century. Its central bay is canted forward with a porch, a round-headed first-floor window and a pair of small round-headed windows above, under a segmental gable. A triangular two-faced clock by John Chancellor of Dublin was installed on the front in 1866.

The building was constructed as a jail by Naas Corporation in 1796 and served that purpose for decades. In 1854, the Naas Town Commission acquired it and transformed it into municipal administrative offices.

The Irish name Halla an Bhaile Nás na Ríogh links the building to the town's Irish name, Nás na Ríogh. The hall hosted a concert by songwriter Percy French on 18 May 1915, and on 15 April 1918 a demonstration against conscription was held outside it, attended by MP John O'Connor.

The building stands in the town center and is easy to find when walking through the main streets. Visitors can view the exterior and the distinctive clock at any time without needing permission or advance arrangements.

The triangular clock with two faces on the front was made by John Chancellor of Dublin and installed in 1866, paid for by public subscription. The building also held a Carnegie library on the ground floor to the right of the doorway after the 1905 reopening.
