Comcomly (or Concomly) (1765 – 1830) was a leader of the Native American Chinookan people. Referred to as "Chief" or "'King" Comcomly in contemporaneous journals, he was the principal leader of the Chinook Confederacy, which extended along the Columbia River from the Cascade Range to the Pacific Ocean.
Washington Irving described him in his book Astoria as "a shrewd old savage, with but one eye," and referred to his trade and diplomacy skills. Modern historian James Ronda characterizes Comcomly as a talented diplomat and shrewd businessman. He was friendly to the British and Euro-American explorers whom he encountered, including Robert Gray and George Vancouver, and he received peace medals from Lewis and Clark. He also assisted the Pacific Fur Company, also known as the Astor Expedition, and offered to help the Americans fight the British during the War of 1812, but Astoria was sold to the British instead. Comcomly was friendly with the British as well. He was entertained at Fort Vancouver by John McLoughlin and he piloted Hudson's Bay Company ships up the Columbia.
Comcomly's daughter Elvamox, also known as Marianne, married Duncan McDougall of the Pacific Fur Company, and after he left she married Etienne Alexis Aubichon, also a fur trader. She was the mother of one son and six daughters. Another of Comcomly's daughters, Raven, also known as Princess Sunday, married Archibald McDonald. She was the mother of Ranald MacDonald.
