John Norris Hewett (c. 1745 – 1790), born Fisher, was a female English art collector and amateur artist.
Also unknown is the origin of her unusual forename, though it has been suggested that it was chosen to placate her grandfather, Admiral John Norris, after her mother remarried against his wishes.
In 1773 she married Admiral John Storr, acquiring from him a house in Bedford Square and a life interest in a number of Yorkshire estates.
These were largely copies, after such painters as Angelika Kauffmann, John Reynolds, Guido Reni, William Peters, and Russell.
None are known to survive, save potentially one, a copy of The Resurrection of a Pious Family by Peters, which turned up at auction in 2015 with no attribution.
