911 Agamemnon is a large 167 kilometres (104 mi) trojan asteroid that orbits the Sun at the same distance as the planet Jupiter. It is located in the leading Lagrangian point L4. Based on IRAS data, Agamemnon is 167 kilometres (104 mi) in diameter and is probably the 2nd largest Jupiter Trojan. Recent observations of the asteroid's occultations characterize its shape and are suggestive of Agamemnon to have a satellite.

It was discovered by Karl Wilhelm Reinmuth on March 19, 1919, in Heidelberg, Germany. It is named after King Agamemnon, a main character of the Iliad.

Photometric observations of this asteroid during 1997 were used to build a light curve showing a rotation period of 6.5819 ± 0.0007 hours with a brightness variation of 0.29 ± 0.01 magnitude. A 2009 study yielded a period of 6.592 ± 0.004, in reasonable agreement with the previous result.
