In the early years of the European discovery and exploration of the New World, the land that became Trumbull County was originally claimed by French explorers as part of the French colony of Canada (New France). Their settlements had some fur traders who interacted with Native American tribes in this area. After losing the Seven Years' War to Great Britain, France was forced to cede its territories east of the Mississippi River in 1763. Great Britain renamed New France as the Province of Quebec.
Following the United States' victory in its Revolutionary War, the British were forced to cede this land to the new nation. The federal government convinced Connecticut to give up its claim to the land, but it was known as part of the Connecticut Western Reserve in the Northwest Territory. Connecticut retained sovereignty over some of the eastern portion of what became Ohio, selling this area in 1795 to the Connecticut Land Company, a speculative private development firm. As first organized, Trumbull County consisted of the entire area of the Connecticut Western Reserve before population increased, and it was divided into smaller counties.
The county is named for Jonathan Trumbull, Governor of Connecticut, who once owned the land in this region.  Early settlements were made along the Mahoning River and other waterways, which provided transportation access and water power to the industries that developed later in the 19th century.
According to the U.S. Census Bureau, the county has a total area of 637 square miles (1,650 km2), of which 618 square miles (1,600 km2) is land and 18 square miles (47 km2) (2.9%) is water.  It is approximately a square with sides of 25 miles; it is the only square county in Ohio.
