Esaias Reusner (the Younger) (29 April 1636, Löwenberg in Silesia, now Lwówek Śląski, Poland - 1 May 1679, Berlin, Germany) was a German lutenist and composer.
His first lute teacher was his father Esaias (lutenist to the Prince of Bernstadt). He was a child prodigy and together with his father he traveled and performed at various courts. He wrote two collections of lute suites - Deliciae testudinis and Neue Lauten-früchte. In the years from 1655 to 1672, he was in the service of the duke of Silesia. Thereafter, he worked for a short time as a flute and lute teacher at the University of Leipzig. Finally in 1674, he was appointed chamber lutenist at the court of Frederick William, Elector of Brandenburg in Berlin, where he remained until his death.
He is considered to be one of the best lute virtuosos of his time and one of the first great masters of the 11-course baroque lute in Germany.
