Zaha Hadid Architects is British architecture and design firm founded by Zaha Hadid (1950–2016), with its main office situated in Clerkenwell, London. After the death of "starchitect" Hadid, Patrik Schumacher became head of the firm, at the time with a staff of 400 with 36 projects across 21 countries.

Dame Zaha Mohammad Hadid was an Iraqi-British architect, artist and designer, recognized as a major figure in architecture of the late-20th and early-21st centuries. Born in Baghdad, Iraq, Hadid studied mathematics as an undergraduate and then enrolled at the Architectural Association School of Architecture in 1972. In search of an alternative system to traditional architectural drawing, and influenced by Suprematism and the Russian avant-garde, Hadid adopted painting as a design tool and abstraction as an investigative principle to "reinvestigate the aborted and untested experiments of Modernism [...] to unveil new fields of building".
