Telemaco, ossia L'isola di Circe is a 1718 opera by Alessandro Scarlatti to a libretto by Carlo Sigismondo Capece (sometimes spelled "Capeci"), court poet to Queen Maria Casimira of Poland, living in exile in Rome, for the Teatro Capranica in Rome, where it was premiered during the carnival season.

The libretto was written by Carlo Sigismondo Capece, based on Homer's Odyssey and François Fénelon's didactic novel Les Aventures de Télémaque.

Telemaco is known for a richness in melodies, contrasting characters, and a colourful orchestral treatment which includes dense textures and counterpoint.

The entrance of Neptune is accompanied by horns, oboes, and bassoon on stage, while Minerva enters in a chariot which holds a string orchestra with trumpets.

Thomas Hengelbrock rediscovered the score at the Austrian National Library in Vienna and prepared it for a performance.
