Benjamin Whitworth (24 May 1816 – 24 September 1893) was an Irish politician who represented constituencies in Ireland at the United Kingdom Parliament in Westminster, London.
He came to Drogheda as a child; his father was an English corn merchant, and his mother was an Irish seamstress.
However his 1868 re-election was declared void and he was replaced by his son Thomas Whitworth, in an unopposed by-election on 15 March 1869.
In 1865 he built the Whitworth Hall, located on St. Laurence's Street, which he later donated to the people of the town.
John Porter dedicated his 1876 publication, History of the Fylde of Lancashire,[6][7] to Whitworth "in admiration of his enterprise, generosity, and philanthropy".
