Jacob Banks (27 February 1704–1738), of Milton Abbas, Dorset, was a British politician who sat in the House of Commons between 1726 and 1738.
Banks was the second son of Sir Jacob Bancks (or Banks), of Milton Abbas, and his wife Mary Tregonwell, only surviving daughter of John Tregonwell, MP of Milton Abbas.
Banks's father was originally a Swedish diplomat who served in the Royal Navy, and his mother was formerly married to Francis Luttrell.
[1] Banks was returned as Member of Parliament for Christchurch at a by-election on 9 April 1726, probably as a Tory, but he lost his seat at the 1727 general election and petitioned unsuccessfully.
He also died intestate, and a complex lawsuit arose, involving the Swedish side of the family.
