The Heidrun oil field is an oil and gas field discovered in 1985 in the Norwegian sector of the Norwegian Sea, named after the goat Heiðrún from Norse mythology.

The field lies {{convert|175|km}} north of Kristiansund. It has produced oil and gas since October 1995. In 2013, it produced 65,000 barrel of oil per day and 760 million cubic meters of natural gas.[http://www.offshore-technology.com/projects/heidrun-field Offshore Technology] The crude oil is characterized as being naphthenic with 25.0 API (0.9043 g/cm³), 0.52% sulfur, and a high TAN (Total Acid Number) of 2.90.

The Heidrun field is located on Haltenbanken in the Norwegian Sea at a depth of {{convert|350|m}}. The field has been developed with gas and water injection, using a floating concrete tension leg platform, installed over a subsea template with 58 well slots.{{cite journal |url= https://pubs.geoscienceworld.org/books/book/1336/chapter/107171107/the-geology-of-heidruna-giant-oil-and-gas-field-on |last=Whitley |first=P.K. |title=The Geology of Heidrun: A Giant Oil and Gas Field on the Mid-Norwegian Shelf |year=1992 |journal=Giant Oil and Gas Fields of the Decade, 1978-1988 |volume=54 |publisher= American Association of Petroleum Geologists |isbn=0891813330 |pages=383–406}} The northern part of the field is developed with subsea facilities.
