William Lewis Paul (May 7, 1885 – March 4, 1977) was an American attorney, legislator, and political activist from the Tlingit Nation in Southeast Alaska.

The organization pressed for voting rights, desegregation, and social services, as well as advancing the first Tlingit and Haida land claims in Alaska.

His first run for the House in 1922/1923 was challenged legally and became an ultimately successful test case on citizenship rights of Indians to vote and hold office.

Paul was defeated in his third run for the seat, in 1928, partly because of accusations that he had received payments from the salmon canning industry that he had vilified repeatedly in print.

In the 1950s Paul brought an important land claims test case, Tee-Hit-Ton vs. U.S., on behalf of his own Tlingit clan, which was unsuccessful but which laid the groundwork for the later ANCSA.
