There are several places in the Netherlands and Germany named Keppel.

The word 'Keppel' itself is thought to be a diminutive of 'kapel' (chapel) or related to 'kop' (head/top), referring to a small hill or mound, often one where a chapel might be located. Over time, descendants of these families or individuals from these locations spread, carrying the surname with them. A notable branch of the family, the Earls of Albemarle, are descendants of Arnold Joost van Keppel, who came to England with William of Orange in 1688.
