L'Estro Armonico (Harmonic Inspiration), Op. 3, is a collection of twelvec oncertos for one, two and four violins written by Antonio Vivaldi in 1711. It augmented the reputation of Vivaldi as Il Prete Rosso (The Red Priest). Vivaldi scholar Michael Talbot described the set as "perhaps the most influential collection of instrumental music to appear during the whole of the eighteenth century".
