Daphne or Die Verwandelte Daphne, HWV 4, is an opera composed by Handel for the Oper am Gänsemarkt in Hamburg in 1706, to a libretto by Hinrich Hinsch. The opera, based on the Daphne myth, was the second part of a double opera. Both works were first performed in Hamburg in January 1708. While the music is lost, the libretto survived, and two suites were reconstructed.

Reinhard Keiser was a German opera composer based in Hamburg. He wrote over a hundred operas. Johann Adolf Scheibe considered him an equal to Johann Kuhnau, George Frideric Handel and Georg Philipp Telemann, but his work was largely forgotten for many decades.
