Lille Grönnegade Theatre, was a Danish theatre active in 1722–1728. It was the first public theatre in Copenhagen in Denmark.
In 1721, the French troupe, which had performed for the royal court in Copenhagen since 1682, was fired by the king, who wished to hire an Italian Opera-trope instead. The French actors, who in many cases had lived there for generations, did not all wish to leave Denmark. Rene Magnon and another French immigrant, Etienne Capion, then asked permission to open a Public theatre. They were given royal permission and in 1722, and the first Public theatre was opened in Copenhagen on Lille Grönnegade, the first theatre open to the public in the Danish language.
Capion was the director, Magnon was responsible for the actors, and Marie Madeleine de Montaigu became the first actress to have performed for the Danish Public on an official theatre. The female actors were few; among them were also Helene le Coffre, Maren Magdalene Lerche and Marie Madeleines own daughter Frederikke Sophie. Plays were performed in Danish, but also dance: in 1726, Jean-Baptiste Landé was a guest ballet master.
The economical difficulites, however, proved to be to difficult. In 1728, the theatre was closed, and in 1730, theatre was banned in Denmark until 1746.
