Maris Bryant Pierce (1811–1874; also known as Ha-dya-no-doh, Swift Runner),[1] was a Seneca Nation chief, lawyer, and teacher.

[4] On August 28, 1838, Pierce gave the noted speech Address on the Present Condition and Prospects of Aboriginal Inhabitants of North America, with Particular Reference to the Seneca Nation, delivered in Buffalo, New York about his anti-land removal stance.

[1] After the 1840 United States Senate ratification of the Second Treaty of Buffalo Creek, Pierce continued to fight against the removal.

[4][9] Pierce was under complex pressure as a mediator between the two cultures, and he engaged in the discussion of "European enlightenment" in order to argue against Seneca land removal.

[4][7] The treaty case was not resolved until 1898 (after Pierce's death), the United States government awarded a compensation of $1,998,714.46 to "the New York Indians".
