Minna von Barnhelm or the Soldiers' Happiness (, ) is a lustspiel or comedy by the German author Gotthold Ephraim Lessing. It has five acts, was begun in 1763 and completed in 1767 – its author put the year 1763 on the official title page, presumably to emphasize that the recent Seven Years' War plays a major part in the play, which is set on 22 August 1763. It is one of the most important comedies in German literature. It was first performed in 1767 by the Hamburg National Theatre, where Lessing worked as a dramaturg.
