National Provincial Bank was a British retail bank which operated in England and Wales from 1833 until 1970 when it was merged into the National Westminster Bank. It continued to exist as a dormant non-trading company until 2016 when it was voluntarily struck off the register and dissolved. Considered one of the "Big Five," the National Provincial Bank expanded during the 19th and 20th centuries and took over a number of smaller banking companies. For most of its history it was based on Bishopsgate, at the thoroughfare's junction with Threadneedle Street, in London.
