Tambar (Norwegian: Tambarfeltet) is an offshore oil field located in the southern Norwegian section of North Sea along with Ula and Gyda fields making up the UGT area, usually attributed to DONG Energy's main areas of exploration and production activity.

[3] Aker BP is the operator of the field with 55% share in the project, while DNO holds the remaining 45% stake.

The main reservoir stands at 4,200 m (13,800 ft) in the Upper Jurassic Ula Formation.

It is remotely controlled from the facility at the Ula field which is located 16 km (9.9 mi) southeast of Tambar.

Gas injection is used at Tambar and the produced oil is pumped to Ula facilities via Tambar-Ula pipeline which came online in 2007 and is then transported by a pipeline to Ekofisk oil field and on to Teesside for refining.
