Collin McKinney (April 17, 1766 – September 9, 1861) was an American surveyor, merchant, politician, lay preacher, and prolific slave owner.
From 1818 to 1821, McKinney managed the Tennessee estates of Senator George W. Campbell, who was serving as minister to Russia at the time.
In 1826, McKinney became a friend of Benjamin Milam, who was recruiting settlers for the Red River Colony in Northeast Texas of Empressario and British General Arthur G. Wavell.
The land grant was an area claimed by both the United States settlers as part of Miller County, Arkansas, as well as by Mexico.
In 1846, at age 80, he moved one last time, due to one of the worst known floods on the Red River, to the northern portion of the rich blackland prairie of Collin County, Texas, to be near several of his children.
