Carlo Krahmer (born William Max Geserick, 11 March 1914, Shoreditch, London – 20 April 1976, London) was a British jazz drummer and record producer.
A partially sighted musician, Krahmer joined Claude Bampton's Orchestra, a body sponsored by the National Institute for the Blind (now the RNIB), of which George Shearing was also a member. He worked in various bands, sometimes as leader, taking his own group to the Paris Jazz Festival in 1949.
In 1947 Krahmer co-founded Esquire Records with Peter Newbrook, a label which recorded bebop and licensed American blues and jazz recordings. By 1950, Krahmer had retired from active performance, but had begun to teach aspiring drummers such as Victor Feldman.
