Maurice Onderet (1899-1981) was a Belgian violinist and pedagogue who lived and worked in Canada from 1927-1946 and from 1965-1971. He is best remembered for concerts in Toronto and Montreal where he gave the Canadian premiere of the Sibelius Violin Concerto a formidable piece well beyond the technical ability of most soloists. He also taught at the McGill Conservatory Mons La Louvière and Montreal. His Violin Method Book 3 was the third of the five volumes of his Méthode de Violon subtitled Systéme des Intervales. It was published in 1948 soon after his first return to Belgium.
