Long gallery is an architectural term given to a long, narrow room, often with a high ceiling. In British architecture, long galleries were popular in Elizabethan and Jacobean houses. They were often located on the upper floor of the great houses of the time, and stretched across the entire frontage of the building. They served several purposes: among others, they were used for entertaining guests, for taking exercise in the form of walking when the weather was inclement, and for displaying art collections.

Later long galleries were built in Victorian houses such as Nottingham Castle.
