Paul-Jean-Jacques Lacôme d'Estalenx was a French composer. Between 1870 and the turn of the century he produced a series of operettas and operas-bouffes that were popular both in France and abroad. Interest in his works revived briefly during the First World War, when they were successfully revived in Paris.

Ma mie Rosette is an opéra comique in four acts with music by Paul Lacôme and words by Jules Prével and Armand Liorat. It is set in 16th-century Navarre, ruled by the young and famously amorous Henri of Navarre. His acceptance of refreshment from Rosette, a young woman on a farm, provokes jealousy in her fiancé. The young couple are brought to Henri's court, where they are married and raised to the aristocracy. The King's attentions to Rosette provoke a furious response from her husband. All the events at court turn out to be a dream of the sleeping Rosette. She wakes on her father's farm in time to receive the King who brings her a generous dowry.
