Johannes Matelart (ca. 1538 – 1607) was a Flemish composer of the late Renaissance, active in Flanders, Bonn, and Rome.
Details of his life are relatively sparse. He came from west Flanders, and served as choirmaster in Bonn sometime in the earlier portion of his life. By 1558 he had probably come to Italy, staying until 1562, and in 1565 he took the post of maestro di cappella at the church of San Lorenzo in Damaso, where he remained for over 40 years. A note in a publication of 1596 indicates that he still held the post of choirmaster there, and was living in Rome.
Some of his music has survived, and unusually for a Roman composer, much of it is instrumental. He published a book of music for lute, which included not only 15 fantasias by himself, in tablature, but arrangements of pieces by Cristóbal de Morales, and Francesco Canova da Milano.
