Nathanial Cook "Nathan" Meeker (July 12, 1817 – September 30, 1879) was a 19th-century American journalist, homesteader, entrepreneur, and Indian agent for the federal government.
He is noted for his founding in 1870 of the Union Colony, a cooperative agricultural colony in present-day Greeley, Colorado.
In 1878, he was appointed U.S.
Agent at the White River Indian Agency in western Colorado.
The next year, he was killed by Ute warriors in what became known as the Meeker Massacre, during the White River War.
His wife and adult daughter were taken captive for about three weeks.
In 1880, the United States Congress passed punitive legislation to remove the Ute from Colorado to Uintah and Ouray Indian Reservation in present-day Utah, and take away some land formerly guaranteed them.
The town of Meeker, Colorado and Mount Meeker in Rocky Mountain National Park are named for him.
