The Bank of England £5 note, also known as a fiver, is a banknote of the pound sterling. It is the smallest denomination of banknote issued by the Bank of England. In September 2016, a new polymer note was introduced, featuring the image of Queen Elizabeth II on the obverse and a portrait of Winston Churchill on the reverse. The old paper note, first issued in 2002 and bearing the image of prison reformer Elizabeth Fry on the reverse, was phased out and ceased to be legal tender after 5 May 2017.
