Louis Situwuka Shotridge (April 15, 1883[1] – August 6, 1937) was an American art collector and ethnological assistant who was an expert on the traditions of his people, the Tlingit nation of southeastern Alaska.

Shotridge was educated at the Haines mission school, where he met his wife-to-be, Florence Dennis (Kaatkwaaxsnéi, also spelled as Katwachsnea), whom he married in a traditional Tlingit arranged marriage; she was of the Lukaax.ádi clan.

Florence became an accomplished weaver of baskets and Chilkat blankets and performed her technique at the Lewis and Clark Centennial Exposition in Portland, Oregon, in 1905.

Forty-nine were sold to George Byron Gordon of the University of Pennsylvania Museum of Archaeology and Anthropology in Philadelphia, who subsequently hired him to collect more, thus beginning a lifelong career for the Shotridges as artifact collectors, art producers, and culture-brokers.

In the early 1930s Louis married again, to Mary Kasakan (Kaakaltin), a Tlingit of Sitka, Alaska of the Kiks.ádi clan from the family of "Chief Katlean", and had two more children by her.
