Alwin Georg Kulenkampff-Post (23 January 1898 – 4 October 1948) was a German virtuoso violinist. One of the most popular German concert violinists of the 1930s and 1940s, he was considered one of the finest violinists of the 20th century.

Robert Schumann's Violin Concerto in D minor, WoO 1, written in 1853, was his only violin concerto and one of his last significant compositions. It remained unknown to all but a very small circle for more than 80 years after it was written.
