The Blue Sulphur Springs Pavilion is an 1834 Greek Revival structure located in Blue Sulphur Springs, West Virginia. The Pavilion is the only surviving structure from the Blue Sulphur Springs Resort mineral spa. The Pavilion consists of twelve columns supporting a square roof, and is primarily built with brick. It was added to the National Register of Historic Places on October 29, 1992.

The Pavilion is built on a square brick foundation with stone facing. The sides measure 32 feet and 10 inches. Twelve columns rest on the foundation, giving the Pavilion an open structure; the columns are of a modified Doric Order and are built of brick covered in plaster. The frieze of the Pavilion is un-decorated and made of clapboard.

​The Pavilion is topped with a four-sided hipped roof with clapboard pediments. The sulphur spring flows into the basin at a rate of 6 gallons per minute and a temperature of 58 degrees Fahrenheit. The Pavilion is the only resort pavilion in West Virginia. In his 1846 book on mineral springs, William Burke described the Pavilion as "well-designed, but badly executed" and referred to the fountain inside as "one of the most beautiful objects imaginable."

​In April of 2013, Rebecca Fleshman Lineberry donated the pavilion and surrounding two acres to the Greenbrier Historical Society. That same year, The Friends of the Blue  began restoration of the structure. The Friends publicized the poor condition of the pavilion, and raised funds for restoration. In 2013, the Historic Preservation Alliance identified the Blue Sulphur Springs as one of the most endangered historic resources in the state.

​In 2020e the foundation of the pavilion was stabilized and drainage was provided to the site. This work was possible thanks to a SHPO grant and the James F.B. Peyton Fund, along with individual contributions.

On July 1st, 2023 the Blue Sulphur Springs Pavilion was re-dedicated by the Friends of the Blue Committee. The Pavilion is open to the public for viewing from 8AM-5PM daily.
