Hallway in Luhrs Tower, 1929 office building in Phoenix, Arizona
Corridor inside a Government Medical College in Kollam, India

A hallway, passage, passageway or corridor is an interior space in a building that is used to connect other rooms. Hallways are generally long and narrow.[1]

Hallways must be sufficiently wide to ensure buildings can be evacuated during a fire, and to allow people in wheelchairs to navigate them. The minimum width of a hallway is governed by building codes. Minimum widths in residences are 36 inches (910 mm) in the United States.[2] Hallways are wider in higher-traffic settings, such as schools[3] and hospitals.[4]

In 1597 John Thorpe is the first recorded architect to replace multiple connected rooms with rooms along a corridor each accessed by a separate door.[5]
