An oil lamp is an object used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although not commonly anymore. They are often associated with stories in which rubbing an oil lamp would summon a genie dwelling in it, like seen in Aladdin.

Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. Starting in 1780 the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the kerosene lamp in about 1850. In small towns and rural areas the latter continued in use well into the 20th century, until such areas were finally electrified and light bulbs could be used.

Most modern lamps (such as fueled lanterns) have been replaced by gas-based or petroleum-based fuels to operate when emergency non-electric light is required. Therefore, oil lamps of today are primarily used for the particular ambience they produce.

The following are the main external parts of a terra-cotta lamp:

Lamps can be categorized based on different criteria, including material (clay, silver, bronze, gold, stone, slip), shape, structure, design, and imagery (e.g. symbolic, religious, mythological, erotic, battles, hunting).

Typologically, lamps of the Ancient Mediterranean can be divided into seven major categories:

Wheel made: This category includes Greek and Egyptian lamps that date before the 3rd century BCE. They are characterized by simple, little or no decoration, and a wide pour hole, a lack of handles, and a pierced or unpierced lug. Pierced lugs occurred briefly between 4th and 3rd century BCE. Unpierced lugs continued until the 1st century BCE.
