The Hicks Building is a building in the city of Sheffield, South Yorkshire, England, part of the University of Sheffield. It is named in honour after William Mitchinson Hicks.
The building houses the departments of Physics and Astronomy, the Chemistry and Physics Workshop (formally known as the Central Mechanical Workshops) and the School of Mathematics and Statistics, which comprises the departments of Probability and Statistics, Applied Mathematics and Pure Mathematics. It is in three sections: a taller building, with a roof height of around 40 metres (130 ft), clad in red-brick; a shorter, fully linked section which is only around 12 metres (39 ft) tall, clad in blue tiles and glass; and a section facing the University Concourse, around 15 metres (49 ft) tall, clad in blue, following a re-paint in 2010. It was built in the 1950s, but was reclad to give it a more modern appearance and because the old cladding was in a poor state of repair. The smaller section was also reclad, in 2006.
The building has long been one of the city's taller buildings, and has dominated the site to the south of Western Bank (the Arts Tower, Sheffield's second tallest building, is on the northern side, though closer to Bolsover Street) until the completion of the shorter, copper-clad Information Commons, adjacent to Upper Hanover Street.
