The William A. Buckingham House, also known as Buckingham Memorial Hall, is a historic house a fraternal hall at 307 Main Street in Norwich, Connecticut. It is a 2-1/2 story brick structure, with a main block three bays wide, topped by a hip roof with a steep gable above the main entrance. It was built in 1847 by William A. Buckingham, whose later political career included terms as mayor of Norwich and Governor of Connecticut (the latter during the American Civil War). Buckingham is known to have had both Abraham Lincoln and Ulysses S. Grant as guests. The house was purchased in 1898 by the local chapter of the Grand Army of the Republic, a Civil War veterans organization. It has since been converted into a senior center.
