Nathaniel Collins McLean (February 2, 1815 – January 4, 1905), was a lawyer, farmer, and Union general during the American Civil War.

Born in Warren County, Ohio, Nathaniel McLean was the son of John McLean, an 1856 and 1860 Republican presidential candidate and Associate Justice of the Supreme Court of the United States known as "the politician of the Supreme Court".

McLean was well educated, and graduated from Augusta College in Kentucky at the age of sixteen. He then attended Harvard College and received his J.D. He was married in 1838 to Caroline Thew Burnett, the daughter of a Cincinnati judge. While practicing law, he fell ill, and he was advised to travel to Europe and attempt to regain his health. Shortly after his trip, his wife died. He remarried in 1858 to a woman from Louisville, Kentucky.

At the beginning of the Civil War, McLean organized the 75th Ohio Volunteer Infantry Regiment under authority from Maj. Gen John C. Frémont and became its colonel September 18, 1861. McLean, with Lieutenant-Colonel R.A. Constable and Major Robert Reily, organized and trained the 75th in Wyoming, Ohio, (north of Cincinnati) at Camp John McLean, which he of course named after his father. The regiment was organized into a brigade commanded by Brig. Gen Robert Milroy and assigned to duty in western Virginia under Frémont and the Mountain Department.
