Mathieu Crickboom (2 March 1871 – 30 October 1947) was a Belgian violinist, who was born in Verviers (Hodimont) and died in Brussels.
Crickboom was the principal disciple of Eugène Ysaÿe, who dedicated to him his Sonata for solo violin op.
He lived for a while in Barcelona, where he directed a violin school and a concert society.
The year 1897 saw the formation of Crickboom's own quartet, with Pablo Casals, cello; José Rocabruna, second violin; and Rafael Gálvez, viola.
He edited numerous violin concertos by great composers of the 18th and 19th centuries, but his principal work was his violin method, arranged into progressive etudes, duos, popular melodies and technical themes.
