La Rosmira fedele, also known in modern revivals as Partenope, is a 1725 opera by
Leonardo Vinci. It is largely based on
Domenico Sarro's 1707 setting of Silvio Stampiglia's libretto Partenope but with new arias by Vinci. It was premiered 31 January with Antonia Merighi as Queen Partenope and Faustina Bordoni as Rosmira. Vivaldi set Stampiglia's libretto as a pasticcio Rosmira Fedele in 1738 using arias by Handel, Hasse, Pergolesi, and minor local Venetian composers.
