Aquadrangular castle orcourtyard castle is a type ofcastle characterised by ranges of buildings which are integral with thecurtain walls, enclosing a centralward orquadrangle, and typically with angletowers. There is nokeep and frequently no distinctgatehouse. The quadrangular form predominantly dates from the mid to late fourteenth century and signals the transition from defensively to domestically oriented great houses. The four walls are also known as ranges.

Quadrangular castles typically display a sophisticated and complex approach to the planning of internal social spaces.^[1][2] There are many quadrangular castles around the UK, for example:Bodiam Castle in East Sussex, andBolton Castle.

The 27 quadrangular castles identified by John Rickard as being built in England consist roughly 10% of the castles built in the country between 1272 and 1422. No castles of this design were built in Wales.^[3]

One of the earliest quadrangular castles in Germany isNeuleiningen, of which substantial ruins remain.
