Werner Wolfgang Rogosinski FRS (24 September 1894 – 23 July 1964) was a German (later British) mathematician.

Rogosinski was born in Breslau. His father, Hermann Rogosinski was Counsel in Wroclaw. Rogosinski studied at Mary Magdalen School from 1900 until 1913. He attended the University of Breslau, University of Freiburg and University of Göttingen, with Edmund Landau. His studies were interrupted by World War I, in which Rogosinski served as a medic.

Rogosinski focused his studies on pure mathematics, physics and philosophy. His interest was analytical problems, especially in series. His dissertation, "New Application of Pfeiffer's method for Dirichlet's divisor problem", caused a stir in 1922.

In 1923, he went to Koenigsberg, first as a lecturer, becoming an associate professor in 1928. He worked for five years with Richard Brauer, Gábor Szegő and Kurt Reidemeister. Rogosinski and Szegő families became friends. His first book Fouriersche Reihen was published in 1930. It provided a student's introduction to Fourier series. The original was translated into English in 1950 and is still used.

Rogosinski married in 1928 in Königsberg. In 1932, his son Peter was born. After the Nazi takeover, his fortunes changed. In 1936, his teaching credentials were withdrawn. He was allowed only in some Jewish schools in Berlin. The Cambridge professors G. H. Hardy and John Edensor Littlewood invited him to come to the United Kingdom. He moved with his wife and child to Cambridge in 1937, with support from the Society for the Protection of Science and Learning.
