The Gross Lohner (also spelled Gross Loner, German: Great Lohner), is a limestone mountain of the Bernese Alps , located between Adelboden and Kandersteg in the Bernese Oberland. The main summit has an elevation of 3,048 metres (10,000 ft) above sea level and is distinguished by the name Vorder Lohner ("Fore Lohner"). The mountain features several other peaks, from east to west:

The Lohner range is located east of Adelboden in the Engstlige valley and southwest of Kandersteg in Kander valley. The Gross Lohner is separated from the Chlyne Lohner (Small Lohner) to the north by the Bunderchrinde Pass, which provides a hiking route between Adelboden and Kandersteg.

The first tourist to climb the Lohner was one C. Dürheim from Bern in July 1876. In August of the same year, four members of the Alpine Club, during another ascent, found a bottle with the names of the two Kandersteg mountain guides Ogi and Hari, dated 1875.
