In Little Ilford, Jack Cornwell Street and a nearby block of council flats called John Cornwell VC House are named in his memory. In Jack Cornwell Street there is a public house named The Victoria Cross to commemorate his medal. A blue plaque has been erected by the London Borough of Waltham Forest on the flats that now occupy the site of his birthplace in Clyde Place, Leyton. The 5.5-inch gun on which he served is still displayed in the Imperial War Museum, London. In September 2006, Jack Cornwell VC featured on one of a series of Royal Mail postage stamps marking the 150th anniversary of the Victoria Cross. In 2016, Jack Cornwell was featured on a £5 coin (issued in silver and gold) in a six-coin set commemorating the Centenary of the First World War produced by the Royal Mint. Cornwell Close, on Grimsby's Nunsthorpe Estate and Cornwell Court in Haslemere Road, Portsmouth are named after him.
