Elaeis oleifera × guineensis, also known as the OxG palm, is a human-engineered interspecific hybrid of the American oil palm (Elaeis oleifera) and the African oil palm (Elaeis guineensis). Developed primarily in Latin America, this hybrid represents a critical advancement in tropical agro-forestry and sustainable oil production. The African oil palm (E. guineensis) is the world’s most efficient producer of vegetable oil, prized for its high yield, but it is highly susceptible to devastating pathogens like "bud rot" disease in the Americas. By cross-breeding it with the American oil palm (E. oleifera)—a species native to the Amazon and Central American rainforests that possesses natural resistance to these diseases and a slower vertical growth habit—researchers created a hybrid that merges the high productivity of the African variety with the resilience and management advantages of the American variety.

The hybrid palm is physically distinct, featuring shorter, sturdier trunks that make harvesting significantly easier and safer for laborers compared to the soaring, sometimes 15-meter-tall traditional E. guineensis. The leaves are broad and exhibit a characteristic color and structural morphology inherited from both parents. The fruit bunches are produced on shorter stalks, and the fruit itself contains a higher proportion of pulp (mesocarp) relative to the inner kernel, which is highly advantageous for industrial oil extraction. This palm is grown primarily in equatorial Latin America, where it has become a cornerstone of "smart" plantation management, allowing farmers to maintain high output levels in regions where traditional African palms fail due to regional environmental pressures.

As a food source and industrial product, this hybrid is cultivated exclusively for the production of vegetable oil. The resulting oil is exceptionally high in unsaturated fatty acids, specifically oleic acid, giving it a chemical profile that is healthier and more similar to olive oil than traditional palm oil, which is typically much higher in saturated palmitic acid. Because the oil remains liquid at lower temperatures and has a distinct flavor profile, it is becoming increasingly popular for artisanal culinary applications and specialized food manufacturing. In regions where these palms are cultivated, the extraction of the oil—often performed via traditional small-scale pressing or modern mechanical milling—is a vital economic activity that supports local food security and rural livelihoods.

Nutritionally, the oil extracted from E. oleifera × guineensis is a dense source of energy, but its value lies in its high concentration of beneficial micronutrients. It is significantly richer in carotenoids (specifically beta-carotene) and tocopherols (Vitamin E) than standard refined palm oil. These compounds act as potent antioxidants within the human body. The specific fatty acid composition—higher in monounsaturated fats—is increasingly studied for its potential to help manage cardiovascular health markers when used as a dietary fat. Furthermore, the oil provides a stable medium for frying and food processing without the need for extensive chemical hydrogenation, which helps minimize the formation of harmful trans-fats in the final food product.
