Joaquín Martínez de la Roca (Zaragoza, c. 1676 - Toledo, 1747 or 1756) was a Spanish composer.

In 1715, when he was organist of Valencia Cathedral, Martínez initiated the five-year-long pamphlet war against Francisco Valls for the unconventional dissonances in the Miserere of Valls' Missa Scala Arentina.
