Hornsey Town Hall is a public building in Crouch End area of Hornsey, London. Completed in 1935, it was the first major UK building to be constructed in the Modernist style. Designed by New Zealand born architect Reginald Uren in 1933–35, the building shows the influence of Hilversum town hall in the Netherlands and was awarded a bronze medal by the Royal Institute of British Architects. It has Grade II* Listed status. The building was used by Hornsey Borough Council as its headquarters until 1966. Hornsey Town Hall is often referred to by its abbreviation, HTH.
When the former area of the Municipal Borough of Hornsey became part of the London Borough of Haringey most of the administrative functions were re-located at Wood Green. As a result, the building has fallen into disrepair, although steps are being taken to find a new use for the building.
