Jaap Blonk (born 1953 in Woerden, Netherlands) is a self-taught composer and poet. His unfinished studies in mathematics and musicology mainly created a penchant for activities in a Dada vein, as did several unsuccessful jobs in offices and other well-organized systems.

In the early 1980s he discovered the power and flexibility of his voice, and set out on a long-term research of phonetics and the possibilities of the human voice. At present, he has developed into a specialist in the creation and performance of sound poetry, supported by a powerful stage presence. He performs and gives workshops worldwide on a regular basis. With the use of live electronics the scope and range of his work has acquired a considerable extension. From his sound poetry scores he developed an independent body of visual work, which has been published and exhibited.
