Arthur Chichester, 1st Baron Chichester (May 1563 – 19 February 1625), (known between 1596 and 1613 as Sir Arthur Chichester), of Carrickfergus in Ireland, was an English administrator and soldier who served as Lord Deputy of Ireland from 1605 to 1616. He was instrumental in the founding and expansion of Belfast, now Northern Ireland's capital. Several streets are named in honour of himself and his nephew and heir Arthur Chichester, 1st Earl of Donegall, including Chichester Street and the adjoining Donegall Place, site of the Belfast City Hall.
