Leon Sametini (16 March 1886 – 20 August 1944) was an American virtuoso violinist and music pedagogue who originated from Rotterdam, Holland.

[2] He initially studied violin in the Netherlands with his uncle, M. De Groot, and from 1892 until he was 10 years of age with Dutch violinist Felice Togni and Bram Eldering at the Amsterdam Conservatoire.

[2][4] As a violin virtuoso, Sametini gave concert tours from which he became well known in Europe, particularly in the Netherlands, Belgium, England and Austria.

[5] When I was twelve years old, my great teacher Leon Sametini told me to focus my attention on my bow arm.

[9] Whilst director of violin, he taught notable students such as Silvestre Revueltas,[10] Aaron Rosand,[11] Harry Adaskin,[12] Oliver Colbentson [de] and Guila Bustabo, who studied with Sametini from the age of five.
