{{#invoke:Infobox|infobox}} 11 Parthenope<ref>Stressed on the second syllable, {{#invoke:IPAc-en|main}} par-THEN-ə-pee.</ref> is a large, bright main-belt asteroid.

Parthenope was discovered by Annibale de Gasparis on 11 May 1850, the second of his nine asteroid discoveries. It was named after Parthenopē, one of the Sirens in Greek mythology, said to have founded the city of Naples. De Gasparis "used his utmost endeavours to realise a 'Parthenope' in the heavens, such being the name suggested by Sir John Herschel on the occasion of the discovery of Hygiea in 1849".<ref>{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref>

There have been two observed Parthenopian occultations, on 13 February 1987, and 28 April 2006.

On August 6, 2008, during a perihelic opposition, Parthenope had an apparent magnitude of 8.8.

In 1988 a search for satellites or dust orbiting this asteroid was performed using the UH88 telescope at the Mauna Kea Observatories, but the effort came up empty.<ref name="Gradie1988"/>

Based upon a light curve that was generated from photometric observations of this asteroid at Pulkovo Observatory, it has a rotation period of 13.722 ± 0.001 hours and varies in brightness by 0.10 ± 0.0s in magnitude. The light curve displays three maxima and minima per cycle.<ref name="Pilcher2011"/> The JPL Small-Body Database lists a rotation period of 13.7204 hours.<ref name=jpldata/>
