Schillström is a surname of Swedish origin. It is a compound word, with "Schill" possibly deriving from a German personal name or a placename, and "ström" meaning stream or river. This suggests the name may have originated from a place with a stream. Like many Swedish surnames, it is likely to have become more common as a patronymic or occupational name.
The Schillström surname is found primarily in Sweden, although it may also appear in other Nordic countries
