Therese Bertheau (23 November 1861 – March 1936) was a pioneering female Norwegian mountaineer.
She was among the first in modern times to introduce trousers as an everyday item of clothing for women.
In 1900 she was again on Store Skagastølstind accompanied by English mountain climber William Cecil Slingsby (1849-1929).
In August 1901 she completed the first traverse over Styggedalstindane with well-known mountaineers Kristian Tandberg and George Wegner Paus.
