Julio Salvador Sagreras (22 November 1879 – 20 July 1942) was an Argentine guitarist, pedagogue, and composer.
Both his parents were guitarists who taught him the guitar very early – his father was Gaspar Sagreras (1838–1901).
He progressed quickly and became a professor of guitar at the Académia de Bellas Artes in 1899.

[3] In addition to Sagreras' Lecciones ..., other famous works for guitar include Maria Luisa (a mazurka), El Zorzal (Estilo), Violetas (Waltz), and the virtuosic El Colibri.
