Lieutenant General Benjamin Bloomfield, 1st Baron Bloomfield was a British Army officer who saw action at the Battle of Vinegar Hill in June 1798 during the Irish Rebellion. He was Member of Parliament (MP) for Plymouth from 1812 from 1818 and served as Private Secretary to the Sovereign from 1817 to 1822 before becoming Commanding Officer of Woolwich Garrison in 1826.

Plymouth was a parliamentary borough in Devon, which elected two members of parliament (MPs) to the House of Commons in 1298 and again from 1442 until 1918, when the borough was merged with the neighbouring Devonport and the combined area divided into three single-member constituencies.
