Albus or Albinus is a Latin surname, or cognomen, best known as the name of the main branch of the patrician gens Postumia. Albus, the original form of the name, means "white". The lengthened form, Albinus, may be interpreted either as "whitish" or as "little" or "young Albus." We also find in proper names in Latin, derivatives ending in -anus, -enus, and -inus, used without any additional meaning, in the same sense as the simple forms.
