This list of vegetable oils includes all vegetable oils that are extracted from plants by placing the relevant part of the plant under pressure to extract the oil. Although most plants contain some oil, only the oil from certain major oil crops  complemented by a few dozen minor oil crops is widely used and traded.
Oils may also be extracted from plants by dissolving parts of plants in water or another solvent, and distilling the oil. Oils extracted in this manner are called essential oils. Essential oils often have different properties and uses than pressed vegetable oils. Oils can also be made by infusing parts of plants in a base oil a process known as maceration.
Vegetable oils can be classified in several ways, for example:
By source: most, but not all vegetable oils are extracted from the fruits or seeds of plants, and the oils may be classified by grouping oils from similar plants, such as "nut oils".
By use: oils from plants are used in cooking, for fuel, for cosmetics, for medical purposes, and for other industrial purposes.
The vegetable oils are grouped below in common classes of use.
Pecan oil, valued as a food oil, but requiring fresh pecans for good quality oil.
Pistachio oil, strongly flavored oil, particularly for use in salads.
Walnut oil, used for its flavor, also used by Renaissance painters in oil paints.
Oils from melon and gourd seeds
Members of the cucurbitaceae include gourds, melons, pumpkins, and squashes. Seeds from these plants are noted for their oil content, but little information is available on methods of extracting the oil. In most cases, the plants are grown as food, with dietary use of the oils as a byproduct of using the seeds as food.
Bottle gourd oil, extracted from the seeds of the Lagenaria siceraria, widely grown in tropical regions throughout the world. Used medicinally and as an edible oil.
Buffalo gourd oil, from the seeds of the Cucurbita foetidissima, a vine with a rank odor, native to southwest North America.
Pumpkin seed oil, a specialty cooking oil, produced in Austria and Slovenia. Poor tolerance for high temperatures.
Watermelon seed oil, pressed from the seeds of Citrullus vulgaris. Traditionally used in cooking in West Africa.
A number of oils are used as food supplements, for their nutrient content or medical effect.
Acai oil, from the fruit of several species of the Açaí Palm (Euterpe). Grown in the Amazon region. Similar to grape seed oil. They are used in cosmetics and as a food supplement.
Blackcurrant seed oil, used as a food supplement, because of high content of omega-3 and omega-6 fatty acids.
Borage seed oil, similar to blackcurrant seed oil, used primarily medicinally.
A number of the oils listed above are used for biofuel (biodiesel and Straight Vegetable Oil) in addition to having other uses. A number of oils are used only as biofuel.
Although diesel engines were invented, in part, with vegetable oil in mind, diesel fuel is almost exclusively petroleum-based. Rising oil prices have made biodiesel more attractive. Vegetable oils are evaluated for use as a biofuel based on:
Suitability as a fuel, based on flash point, energy content, viscosity, combustion products and other factors
Cost, based in part on yield, effort required to grow and harvest, and post-harvest processing cost
Multipurpose oils also used as biofuel
The oils listed immediately below are all (primarily) used for other purposes - all but tung oil are edible - but have been considered for use as biofuel.
Tung oil, referenced in several lists of vegetable oils that are suitable for biodiesel.
Inedible oils used only or primarily as biofuel
These oils are extracted from plants that are cultivated solely for producing oil-based biofuel. These, plus the major oils described above, have received much more attention as fuel oils than other plant oils.
Milk bush, popularized by chemistMelvin Calvin in the 1950s. Researched in the 1980s by Petrobras, the Brazilian national petroleum company.
Petroleum nut oil, from the Petroleum nut native to the Philippines. The Philippine government once explored the use of the petroleum nut as a biofuel.
Drying oils are vegetable oils that dry to a hard finish at normal room temperature. Such oils are used as the basis of oil paints, and in other paint and wood finishing applications. In addition to the oils listed here, walnut, sunflower and safflower oil are also considered to be drying oils.
Dammar oil, from the Canarium strictum, used in paint as a drying agent. Can also be used as in oil lamps.
Vernonia oil is produced from the seeds of the Vernonia galamensis. It is composed of 73-80% vernolic acid, which can be used to make epoxies for manufacturing adhesives, varnishes and paints, and industrial coatings.
A number of pressed vegetable oils are either not edible, or not used as an edible oil.
Apple seed oil, used in cosmetics for its hydrating properties.
Balanos oil, pressed from the seeds of Balanites aegyptiaca, was used in ancient Egypt as the base for perfumes.
Bladderpod oil, pressed from the seeds of Lesquerella fendleri, native to North America. Rich in lesquerolic acid, which is chemically similar to the ricinoleic acid found in castor oil. Many industrial uses. Possible substitute for castor oil as it requires much less moisture than castor beans.
Brucea javanica oil, extracted from the seeds of the Brucea javanica. Used medicinally.
Chaulmoogra oil, from the seeds of Taraktogenos kurzii, used for many centuries, internally and externally, to treat leprosy. Also used to treat secondary syphilis, rheumatism, scrofula, and in phthisis.
Crambe oil, extracted from the seeds of the Crambe abyssinica, is used as an industrial lubricant, a corrosion inhibitor, and as an ingredient in the manufacture of synthetic rubber.
Cuphea oil, from a number of species of genre Cuphea. Of interest as sources of medium chain triglycerides.
Mowrah butter, from the seeds of the Madhuca latifolia and Madhuca longifolia, both native to India. Crude Mowrah butter is used as a fat for spinning wool, for making candles and soap. The refined fat is used as an edible fat and vegetable ghee in India.
Neem oil, used in cosmetics, for medicinal purposes, and as an insecticide.
Ojon oil, extracted from the nut of the American palm (Elaeis oleifera). Used as a skin and hair treatment. Oil extracted from both the nut and husk is also used as an edible oil in Central and South America.
Orange oil, like lemon oil, cold pressed rather than distilled. Consists of 90% d-Limonene. Used as a fragrance, in cleaning products and in flavoring foods.
Palm oil, extracted from the kernel of the palm fruit. High in saturated fats. Popular in West African and Brazilian cuisine.
Rosehip seed oil, used primarily in skin care products, particularly for aging or damaged skin. Produced in Chile.
Sea buckthorn oil, derived from Hippophae rhamnoides, produced in northern China, used primarily medicinally.
