A bunkhouse is a barracks-like building that historically was used to house working cowboys on ranches in North America. As most cowboys were young single men, the standard bunkhouse was a large open room with narrow beds or cots for each individual and little privacy. The bunkhouse of the late nineteenth century was usually heated by a wood stove and personal needs were attended to in an outhouse.

While the modern bunkhouse today is still in existence on a few large ranches that are too far away from towns for an easy daily commute, it now has electricity, central heating and modern indoor plumbing.

In the United Kingdom, a bunkhouse provides accommodation with fewer facilities than a larger, staffed youth hostel. Bunkhouses are found in mountainous areas, such as the Scottish Highlands, as well as rural areas in England and Wales, for example at All Stretton.
