State capitol building of the U. S. state of Oklahoma

The Oklahoma State Capitol is the house of government of the U. S. state of Oklahoma. It is the building that houses the Oklahoma Legislature and executive branch offices. It is located along Lincoln Boulevard in Oklahoma City and contains 452,508 square feet of floor area. The present structure includes a dome completed in 2002. Oklahoma's first capital was Guthrie, Oklahoma, but it moved to Oklahoma City in 1910. Construction began on the Oklahoma State Capitol in 1914 and was completed in 1917. Originally, it housed the judicial branch of Oklahoma, but the state's high courts moved most of their operations to the Oklahoma Judicial Center in 2011, leaving only the Supreme Court Hearing Chamber in the capitol building. The state capitol complex is the only state capitol grounds in the United States with active oil rigs.

Oklahoma's territorial capital and first state capital was located in the city of Guthrie. The settlement of the first state capital began at noon on April 22, 1889, when cannons sounded the start of the Oklahoma land run. The town was designated as the territorial capital in 1890. Construction on the Oklahoma State Capitol began after a groundbreaking ceremony on July 20, 1914. Architects Soloman Andrew Layton and S. Wemyss Smith were paid $75,000 to develop the architectural plans, while James Stewart & Company received the construction contract. The building's exterior is constructed mainly of Indiana limestone, with a base of local Oklahoma pink granite, and Oklahoma black granite for the grand staircase. The interior prominently features marble as well as fixtures from a variety of sources. While original plans called for a dome, it was omitted due to cost overruns discovered in 1915 when the original $1.5 million appropriated by the Oklahoma Legislature proved insufficient. The building was, however, designed to support a dome. The building was completed on June 30, 1917.

In 1998, state legislators and the governor enacted legislation to create the Oklahoma Centennial Act, which formed the Oklahoma Capitol Complex and Centennial Commemoration Commission. In 2006, plans were made to move the judicial branch into the old Oklahoma Historical Society building, as the agency was moving into the Oklahoma History Center.

The Oklahoma State Capitol, located at 2300 North Lincoln Boulevard, Oklahoma City is composed primarily of white limestone and Oklahoma pink granite. However, the building's dome is made of steel reinforced concrete and reinforced plaster casts. The state capitol complex is famous for its oil wells and remains the only state capitol grounds in the United States with active oil rigs. The capitol building is directly atop the Oklahoma City Oil Field. The state capitol building and the surrounding government buildings, non government agencies, museums, libraries, and tree lined streets and boulevards form the Oklahoma State Capitol Complex or Capitol Campus. The complex includes the State Capitol Park, the Oklahoma History Center, the Oklahoma Judicial Center, and the Oklahoma Governor's Mansion. The mansion has a limestone exterior to complement the Oklahoma State Capitol's exterior. The surrounding neighborhood is home to numerous restaurants and bars. The Oklahoma History Center opened in 2005 and is operated by the Oklahoma Historical Society. It preserves the history of Oklahoma from prehistoric Native American tribes to the present day.

The west wing of the Capitol houses the Oklahoma House of Representatives chamber and offices. The east wing houses
the Oklahoma Senate chamber and offices. The ceremonial office of the governor is located on the second floor. Elected state officials such as the state auditor and inspector, state treasurer, and state attorney general have offices on the first floor. The building also contains a museum, a cafeteria, and a barber shop.

Chickasaw artist Mike Larsen's mural Flight of Spirit, honoring the Five Moons, notable 20th century Native American ballerinas from Oklahoma is on display in the Capitol rotunda. Several large paintings by Wayne Cooper are on display in the building. Many of them depict the early heritage and oil history of the state. Seminole artist Enoch Kelly Haney's painting The Earth and I are One is on display on the first floor of the building. The Senate lobby includes a oil on canvas painting of the Ceremonial Transfer of the Louisiana Purchase in New Orleans 1803 by Mike Wimmer. The Senate Lounge displays a watercolor painting entitled Community of Boling Springs by Sonya Terpening.

The base of the Capitol dome is decorated, in six inch gold letters, with the names of donors who contributed at least $1 million to the dome's construction, referred to as "the ring of honor", a concept usually limited to the most prominent players on professional football teams. Donors so named include Halliburton, Hobby Lobby Stores, "the People of Oklahoma", and General Motors. This design decision attracted some criticism at the time, and in 2011 state representative Eric Proctor attempted to pass legislation replacing the names with those of Oklahomans who had received the Congressional Medal of Honor.
