A Dutch door (American English), stable door (British English), or half door (Hiberno-English) is a door divided in such a fashion that the bottom half (the hatchThe Word Book Dictionary, 1979 / hatch2 / 3) may remain shut while the top half opens. They were known in early New England as double-hung doors.{{fact|date=November 2016}} The initial purpose of this door design was to keep animals out of farmhouses or to keep children inside while allowing light and air to filter through the open top, essentially combining a door with a fairly large window. When the top half was open, they also allowed a breeze, but stopped the wind from blowing dirt into the house.
Uses
This type of door was common in the Netherlands in the 17th century and appears in Dutch paintings of the period. They were also commonly found in the culturally-Dutch areas of New York and New Jersey before the American Revolution.[http://www.metmuseum.org/toah/works-of-art/34.79a,b "Dutch door (American) (34.79a,b)".

Dutch doors were often incorporated into the design of passenger railcars in North America to allow crewmen to interact with employees outside or to carry out visual inspections. In Australia, post-war passenger cars and brakevans were similarly configured. However, those on passenger cars were later converted to conventional doors for passenger safety reasons. In Canada, changes to operating rules{{Ambiguous|reason=Needs to be more specific |date=March 2023}} rendered the Dutch doors obsolete, although older rolling stock retains them.{{Citation needed|date=January 2013}}
Similar doors were once commonplace in Irish houses, called half-doors ({{langx|ga|leathdoras}} or comhla bheag).{{cite web|url=https://www.teanglann.ie/ga/fgb/%22half-door%22|title=Foclóir Gaeilge–Béarla (Ó Dónaill)|website=www.teanglann.ie}} According to The Irish Times, "A traditional half-door is really a door and a half – a full door that opens inwards and a half door set to the front of the frame that opens outwards." They were designed to keep poultry and pigs from entering the house, as well as allowing air and sunlight into the usually dark and smoky cottages.{{cite news|url=https://www.irishtimes.com/life-and-style/homes-and-property/brass-bed-range-dog-get-the-irish-country-cottage-look-1.2999570|title=Brass bed, range, dog: get the Irish country cottage look|newspaper=The Irish Times |publisher=}}{{cite web|url=https://breisebreiseleighgoleire1969.wordpress.com/tag/half-door-of-a-thatched-cottage/|title=Half door of a thatched cottage - Breise!

They have been used internally in residential care homes to control wandering but maintain a line of sight{{cite journal |last1=Verderber |first1=S |title=Residential hospice environments: evidence-based architectural and landscape design considerations. |journal=Journal of palliative care |date=2014 |volume=30 |issue=2 |pages=69-82 |pmid=25058984}} and in child-care environments, but in that context, there are risks of finger-trapping and concerns over fire regulations.{{cite journal |last1=Passantino |first1=Richard J. |last2=Bavier |first2=Robert N. |title=Environmental Quality of Child Day-Care Facilities: An Architect's Point of View |journal=Pediatrics |date=1 December 1994 |volume=94 |issue=6 |pages=1036–1039 |doi=10.1542/peds.94.6.1036}}
