Luke Gardiner (c. 1690 – 25 September 1755) was an Irish property developer and politician.
He was the senior partner in the private bank Gardiner and Hill with Arthur Hill-Trevor on Castle Street until its dissolution in 1739.
[4] During his career Gardiner acquired a wide variety of land and properties throughout Dublin city.
The major continuous part, much of which he purchased from the Moore family in 1714,[5] was a large piece of land to the East of the then established city.
After his death, his son and heir Charles continued the development, finishing Rutland Square before his grandson, Luke Gardiner (later Lord and Viscount Mountjoy) inherited the estate and accelerated the development further East.
