Spies
A surname with several possible origins, most likely either from a medieval nickname or from a Dutch/German patronymic form related to Peter/Pier.
The #9,279 most common surname in the United States (2010 Census) — about 1 in every 88,012 Americans shares it.
Etymology
The surname Spies is tricky because historical sources point in more than one direction. In Dutch and related Germanic naming traditions, forms like Spies have been explained as shortened or worn-down patronymic forms linked to names such as Pieter/Pier/Petrus, rather than to the modern English word "spy." Some older writers also discussed it alongside occupational or nickname-like forms, but the evidence in the excerpts is not strong enough to choose one explanation with confidence.
History
The name appears in Dutch-language surname scholarship as an established family name, with related forms such as Spiers, Speers, Spees, and Speessen discussed together. It also shows up in English-language records as a minority surname in the United States, but the historical excerpts here do not provide a clear single origin story for the American bearers. Because of that, the safest view is that Spies may reflect more than one source family in different places.

Fun fact
A 19th-century Dutch surname study grouped Spies with several related names and treated them as variations of an older name built from Pier/Pieter.
