Elisabeth Sophie of Mecklenburg, Duchess of Brunswick-Lüneburg (20 August 1613 – 12 July 1676) was a German poet, composer and impresario.

She began studying music at the court of her father, Duke John Albert II of Mecklenburg-Güstrow, where was an orchestra known for its use of fine English musicians, such as William Brade.

In 1635, she married the learned Augustus the Younger, Duke of Brunswick-Lüneburg[1] with whom she had two children: Elisabeth Sophie was charged with organizing the court orchestra, and at times worked closely with Heinrich Schütz, who was appointed absentes Kapellmeister in 1655.

She may have collaborated with him on arias in his Theatralische neue Vorstellung von der Maria Magdalena.

The one printed in 1651, Vinetum evangelicum, Evangelischer Weinberg, is believed to have been the first music published by a woman in Germany.
