Jan Koetsier (14 August 1911, Amsterdam, The Netherlands – 28 April 2006, Munich) was a Dutch composer and conductor.
Koetsier studied at the music school in Berlin. From 1942 to 1948, he was director of the Concertgebouw Orchestra in Amsterdam. From 1949 to 1950, he led the resident orchestra in the Hague, and from 1950 to 1966 he was director of the Bavarian Radio Symphony Orchestra in Munich. From 1966 to 1976 he led the band directing course at the music high school in Munich.
As a composer, he wrote chamber music, and orchestral and choral works, as well as the opera Frans Hals. A well-known example of his composition is Brass Symphony from 1979, which is divided into three movements and arranged for a brass dectet.
In 1992, the Jan Koetsier Foundation was established by an endowment from the composer. One of the main responsibilities of the Foundation, which has been based at the Hochschule since 2001, is the organization of the biennial International Jan Koetsier Competition.
