Giovanni Filippo Apolloni was an Italian poet and librettist. Born in Arezzo, he has sometimes been referred to as "Giovanni Apollonio Apolloni", but the second given name is spurious. He served as the court poet to Ferdinand Charles, Archduke of Austria at Innsbruck form 1653 until 1659. On his return to Italy he entered the service of Cardinal Volumnio Bandinelli. After Bandinelli's death in 1667 Appolloni was in the service of the Chigi family in Rome and Siena for the rest of his life. He wrote the librettos for a number of operas, the most well-known of which were Antonio Cesti's L'Argia and La Dori, as well as several oratorios and the texts for cantatas by both Cesti and Alessandro Stradella.
