9907 Oileus is a Jupiter Trojan asteroid of the Greek camp. It orbits the Sun once every 12.23 years.

Discovered on September 24, 1960 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on photographic plates made by Tom Gehrels at the Palomar Observatory with the Samuel Oschin telescope, it was given the provisional designation "6541 P-L". It was later renamed "Oileus" after Oileus, a Greek runner slower only than Achilles.
