Town hall in Rokytnice nad Jizerou, Art Nouveau town hall in Horní Rokytnice nad Jizerou, Czech Republic.

The town hall in Horní Rokytnice nad Jizerou is a historicist and Art Nouveau building from 1902, designed by the Vrchlabí firm of Kleofáš Hollman and Viktor Kraus and built by Josef Hájek of Rokytnice. Its 37-metre tower stands in the northeast corner, with a viewing balcony opened to the public in 2018. The tower roof is wedge-shaped, with a bell roof over the larger oriel and a pyramidal roof over the smaller one.

The town council commissioned the building after Rokytnice's growth around 1900; plans came from Kleofáš Hollman and Viktor Kraus of Vrchlabí, and Josef Hájek of Rokytnice built it for 159,701 Austro-Hungarian crowns. The foundation stone was laid on 12 April 1902 and the building opened on 27 September 1903. The Huťský potok stream was culverted during construction. The tower was renovated in 2017 and opened to the public on 27 September 2018.

The building stands on Dolní náměstí, the lower square of Rokytnice nad Jizerou. Its rooms once held flats, three prison cells, a savings bank and the municipal library; later the Veřejná bezpečnost police force was based here. The tower balcony opened to the public on 27 September 2018, 115 years after the building's ceremonial opening.

The building sits at Dolní náměstí square in the town center and is easy to locate and approach. The tower's viewing platform can be reached by climbing stairs and offers views across the surrounding mountain landscape.

The tower clock was removed in 2017 and replaced by an electric mechanism to make the tower accessible; a new entrance to the tower was built at the same time. On 27 September 2018, the 115th anniversary of the building's opening, the tower was opened to the public.
