Actéon (Actaeon) is a Pastorale in the form of a miniature tragédie en musique in six scenes by Marc-Antoine Charpentier, Opus H.481 & H.481a, based on a Greek myth.

(The work was copied into a Roman-number notebook, which strongly suggests that it was an outside commission; and the overall distribution of voices and instruments does not match that of the Guise ensemble of the time.)

Although the patron and the place of performance remain unknown, the date can be determined with considerable accuracy: the spring hunting season of 1684.

[2] The author of the French libretto is unknown, however the plot is based on a story in Ovid's Metamorphoses.

This story is the same one recounted in the aria "Oft she visits this lone mountain" from Purcell's Dido and Aeneas, first performed in 1689.
