The Concerto gregoriano is a violin concerto by Ottorino Respighi. It is inspired by the history and music of early Christianity, such as plainsong and Gregorian chant. It was written in 1921 and premiered the following year in Rome.
Notable recordings have been made by violinists Lydia Mordkovitch for Chandos and Takako Nishizaki for Marco Polo.
