c. 34) was an Act of the Parliament of the United Kingdom that aimed to improve the protection afforded to ancient monuments in Great Britain.

By the turn of the century, the scope of the earlier legislation was felt to be insufficient, and the Ancient Monuments Act empowered the government's Commissioners of Work and local county councils to protect a wider range of properties.

The Act also allowed these groups to provide public access to ancient monuments, and to financially assist with their conservation.

In 1913, gaps in the legislation between the protection ascribed to monuments under the three previous Acts led to the a royal commission and the passing of the additional Ancient Monuments Consolidation and Amendment Act 1913.

[4] The whole Act was repealed, except so far as it related to Ireland, by section 24 of, and the Second Schedule to, Ancient Monuments Consolidation and Amendment Act 1913, subject to the proviso in section 24.
