Semiramide riconosciuta (Semiramis Recognized) is an Italian opera with serious action, or dramma per musica, by Nicola Porpora, set to a libretto by Metastasio with some textual changes, possibly by Domenico Lalli. The opera was written for some of the finest contemporary singers, and includes a technically demanding series of da capo arias.
The opera was first performed on 26 December 1729 at the Teatro San Giovanni Grisostomo in Venice. Metastasio's libretto had been used in Rome, on 6 February that same year, for another setting of the same title by Leonardo Vinci.
