Jan Kotěra (18 December 1871 – 17 April 1923) was a Czech architect, artist and interior designer, and one of the key figures of modern architecture in Bohemia.

Kotěra was born in Brno, the largest city in Moravia, to a Czech father and German-speaking mother. He studied architecture in Vienna during the waning days of the Austro-Hungarian Empire under the Viennese master Otto Wagner.^[1]

Kotěra returned to Prague in 1897 to help found a dynamic movement of Czech nationalist artists and architects centered on the Mánes Union of Fine Arts. Strongly influenced by the work of the Vienna Secession, his work bridged late nineteenth-century architectural design and early modernism. Kotěra collaborated with Czech sculptors Jan Štursa, Stanislav Sucharda, and Stanislav's son Vojtěch Sucharda on a number of buildings.

As a teacher, Kotěra trained a generation of Czech architects, including Josef Gočár, who would bring Czech modernism to its pinnacle in the years leading up to the Nazi occupation in 1939. Kotěra was one of a number of Czech architects to design the "Bata houses" and Bata shoe factory at East Tilbury, Essex, England.^[2] These are considered Modernist landmarks of industry and a company town.
