Kaumudi-Mahotsava (IAST: Kaumudīmahotsava, "Festival of Moonlight") is a Sanskrit play of uncertain date. It is known from a single manuscript discovered in the present-day Kerala state of India. Its style and language suggest that it was composed around the 3rd century. The portion supposedly containing the name of the playwright is damaged, but the name appears to be a feminine one (read by some scholars as "Vijjakaya"), although this cannot be said with certainty. Several scholars have made attempts to identify the play's characters with historical personalities, but most modern scholars believe it to be a work of fiction.
