The place name in England is derived from the Old English tribal name Hæstingas, meaning "Hæsta's people", "the family/followers of Hæsta", which was later transferred to their settlement.
The family name has two possible sources:
- from the place name
- a patronymic surname derived from the Anglo-Norman personal name Hasten(c), Hastang
The later place names in other countries are named either after people with that family name, or after the town of Hastings in England.
