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. 27 No. 5. In the same vein, Ernest Chausson dedicated his string quartet to Crickboom, who for some years played second violin in the Ysaÿe Quartet.
