- Named for Sir James Chadwick (1891-1974), a British physicist.
- Chadwick was added to a bank of names for future use on the Moon in IAU Transactions XVIB (1976).
- The name was approved for use in connection with the present crater in IAU Transactions XIXB (1985).
- Although the IAU Planetary Gazetteer lists this as a replacement name for De Roy X, the latter name would appear to have never been IAU approved since the farside lettered crater names introduced by Ewen Whitaker were not approved by the IAU until 2006, by which time this crater had been given its present name.
