Erling Kagge (born January 15, 1963) is a Norwegian explorer, publisher, author, philosopher, lawyer, art collector and entrepreneur.

Erling Kagge is the first person in history to reach the North Pole, South Pole and the summit of Mount Everest on foot.

In 1990, Erling Kagge and Børge Ousland became the first to reach the North Pole unsupported. The expedition started from Ellesmere Island on March 8, 1990, and reached the North Pole 58 days later on May 4, 1990. They travelled approximately 800 kilometers on skis, pulling their supplies on sledges.

In 1992 and 1993, Kagge completed the first unsupported and solo expedition to the South Pole, covering the 814-mile (1,310 km) route in 50 days. Kagge started at the northern edge of Berkner Island and had no radio or telephone contact to the outside world for the duration of this expedition, which was featured on the cover of Time magazine on March 1, 1993.

In 1994, Kagge summited Mount Everest, thus becoming the first person to complete the "Three Poles Challenge" on foot.

Kagge has also sailed across the Atlantic twice, rounded Cape Horn and sailed to Antarctica and back.

Kagge continues to do expeditions, although with a lower profile than in the 1990s. In 2010, Kagge crossed Vatnajökull ice-cap in Iceland with Børge Ousland and Haraldur Örn Ólafsson.

In 2023, together with Børge Ousland and Håvard Tjora, he became the first to cross White Island on skis, an island in the Svalbard Archipelago.
