Kasaan /kəˈsæn/ (Haida: Gasa'áan; Tlingit: Kasa'aan) is a city in the Prince of Wales-Hyder Census Area in the U.S. state of Alaska.

[4] Beginning in the late 1700s, European and American ships began regularly visiting and trading with Kasaan and the rest of the Haida.

This trade brought wealth, but also disease; the first smallpox epidemic hit Kasaan in 1794.

[4] A rough census was taken of Kasaan between 1836 and 1841 by John Work of the Hudson's Bay Company.

[4] In the 1880s and 1890s, Alaska Steamship Company boats regularly visited a nearby fish saltery and packing business, and sometimes Kasaan.

Tourists visiting Kasaan helped spark trade in Haida artifacts and new artwork.

[4] Residents moved from their former village on Skowl Arm (now called Old Kasaan), starting in 1893, and mostly in the period 1902–1904.

[4] This migration was prompted by the promise of jobs and a school occasioned by development of copper mining and a cannery near the present location.

[4] It became Forest Service jurisdiction, which established a 38-acre Old Kasaan Village Historical Area in 1957.
