Schieffelin Hall is a building from the American Old West in Tombstone, Arizona Territory, the largest standing adobe structure still existent in the United States southwest. It was built in 1881 by Albert Schieffelin, brother of Tombstone founder Ed Schieffelin, and William Harwood as a first class opera house, theater, recital hall, and a meeting place for Tombstone citizens.

Tombstone is a city in Cochise County, Arizona, United States, founded in 1879 by prospector Ed Schieffelin in what was then Pima County, Arizona Territory. It became one of the last boomtowns in the American frontier. The town grew significantly into the mid-1880s as the local mines produced $40 to $85 million in silver bullion, the largest productive silver district in Arizona. Its population grew from 100 to around 14,000 in less than seven years. It is best known as the site of the Gunfight at the O.K. Corral and presently draws most of its revenue from tourism.
