Hibernian Oil was an oil company stationed on Earth in the 20th century. It was based in Tulloch, Scotland. The Duke of Forgill owned all of Tulloch except their shore base.

Its rigs were being destroyed by an unknown force. The Fourth Doctor later discovered that the rigs were being destroyed by the Zygons and the Skarasen.

Huckle and Munro were among their employees. Lamont also worked in their infirmary in Tulloch. (TV: Terror of the Zygons)
