The county was formed on March 8, 1862, although its government was not organized at that time. In 1872 the organization was effected. It was named for nineteenth-century political figure Henry Clay,  member of the United States Senate from Kentucky, and US Secretary of State. The county was originally called Breckenridge, but soon (in 1862) was changed to Clay.
Clay County lies on the west side of Minnesota. Its west boundary line abuts the east boundary line of the state of North Dakota (across the Red River). The Red River flows northward along the west boundary line of the county, on its way to the Hudson Bay in Canada. The Buffalo River flows west-northwesterly through the center of the county, joined by the South Branch Buffalo River west of Glyndon, before discharging into the Red on the county's west border near Georgetown. The terrain consists of rolling hills, dotted with lakes and ponds in its eastern portion.  The terrain slopes to the west and north, with its highest point near the SE corner, at 1,430' (436m) ASL.  The county has a total area of 1,053 square miles (2,730 km2), of which 1,045 square miles (2,710 km2) are land and 7.3 square miles (19 km2) (0.7%) are covered by water.
