Ohio Stadium is the home of the Ohio State Buckeyes football team and is located on the campus of The Ohio State University in Columbus, Ohio. The stadium was added to the National Register of Historic Places by the National Park Service on March 22, 1974. With a capacity of 102,329, it is the fourth largest football stadium in the United States and the seventh largest non-racing stadium in the world. It is popularly known as "The Horseshoe" because of its open south end.

Ohio Stadium provided a home to Major League Soccer team Columbus Crew from the league's inception in 1996 until soccer-specific Columbus Crew Stadium opened in 1999. Ohio Stadium is also a concert venue. U2, The Rolling Stones, Pink Floyd & Metallica are among the many acts who have played at Ohio Stadium.

The stadium does not have field lights. When night events do occur, special lighting must be temporarily installed (as in the 2005 game against Texas and the 2006 nationally televised game versus Michigan).

As early as 1913, Ohio Field at High Street and Woodruff Avenue was unable to contain the crowds attracted to many Buckeye home football games. This led to faculty discussion of moving the site elsewhere and building a new facility. The growing popularity of football in Ohio led to the design of a horseshoe-shaped stadium, conceptualized and designed by architect Howard Dwight Smith in 1918. A public-subscription Stadium Campaign to fund the project began in October 1920 and raised over $1.1 million in pledges by January 1921, of which $975,001 were actually honored.

Ohio (ⁱ/oʊˈhaɪ.oʊ/) is a state in the Midwestern United States. Ohio is the 34th most extensive, the 7th most populous, and the 10th most densely populated of the 50 United States. The state's capital and largest city is Columbus.

The name "Ohio" originated from Iroquois word ohi-yo’, meaning "great river". The state, originally partitioned from the Northwest Territory, was admitted to the Union as the 17th state (and the first under the Northwest Ordinance) on March 1, 1803. Although there are conflicting narratives regarding the origin of the nickname, Ohio is historically known as the "Buckeye State" (relating to the Ohio buckeye tree) and Ohioans are also known as "Buckeyes".

The government of Ohio is composed of the executive branch, led by the Governor; the legislative branch, which comprises the Ohio General Assembly; and the judicial branch, which is led by the Supreme Court. Currently, Ohio occupies 18 seats in the United States House of Representatives. Ohio is known for its status as both a swing state and a bellwether in national elections.
