পিঙ্গো হলো মেরু এবং এর কাছাকাছি অঞ্চলে পাওয়া এক ধরণের বরফের স্তূপ যা মাটির নিচে চাপা পড়ে থাকে। এটা ৭০ মিটার পর্যন্ত হয়ে থাকে ।

A pingo, also called a hydrolaccolith, is a mound of earth-covered ice found in the Arctic and subarctic that can reach up to 70 metres (230 ft) in height and up to 600 m (2,000 ft) in diameter. The term originated as the Inuvialuktun word for a small hill. A pingo is a periglacial landform, which is defined as a nonglacial landform or process linked to colder climates.
