Arlequin roi de Serendib is a three-act farce by Alain-René Lesage.

After being marooned on the island of Serendib, Pierrot and Mezzetin are separated from Arlequin.

Pierrot and Mezzetin, being familiar with the customs of the island, disguise themselves as women to avoid being killed and are appointed priestesses by the natives.

Arlequin enjoys some of the perks of kingship, including fancy meals, a formal portrait sitting, concubines, and a personal physician, before he discovers that the natives sacrifice their kings to their gods.

Before the sacrifice, however, Mezzetin creates a diversion, as he too would like to escape from Serendib where he is being courted by the Grand Visir.
