The Oeiras International Cross Country (Portuguese: Crosse Internacional de Oeiras) is an annual cross country running competition that takes place in Oeiras, Portugal. Established in 2000, it is usually held in mid-November and is traditionally the first competition of the IAAF's cross country season, which culminates each year in the IAAF World Cross Country Championships.

The Oeiras Cross Country has featured athletes such as Kenenisa Bekele, Paul Tergat, Gebregziabher Gebremariam and Felix Limo. The race can be of high importance to Portuguese athletes as the results are often used to decide the national squad for the European Cross Country Championships. The men's race is 9 kilometres long, while the women's race is held over 5 km. In addition to the professional senior races, there are also a number amateur races, including shorter cross country races for children, as well as junior and veteran races.

The course in Jamor is adjacent the Estádio Nacional, the home ground of Portugal's national football team, and is the same circuit that was used for the 1997 European Cross Country Championships and the men's 1999 European Club's Cross Country Cup in 1999. It is a long and hilly course which features a green, scenic setting. The competition is organised by the same group which sets up the Lisbon Half Marathon and the Portugal Half Marathon – the Maratona Clube de Portugal.
