Jankowski is a Polish-language surname derived from the diminutive Janek of the given name Jan. The name is associated with noble szlachta families, landed gentry, and numerous families across Poland, Ukraine, Belarus, Lithuania, Germany, United States, Canada, Brazil, Argentina, Australia and Israel. It appears in records from the Polish–Lithuanian Commonwealth through modern civil registries and passenger manifests.

Etymology

The surname originates from the Slavic personal name Jan (Latinized as Johannes), itself from John; the suffix -owski indicates a toponymic or patronymic association common in Polish onomastics. Nobiliary usage appears alongside coats of arms such as Jastrzębiec (coat of arms), Rawa (coat of arms), Sulima (coat of arms) and Nałęcz (coat of arms) in armorials compiled during the era of the Polish–Lithuanian Commonwealth and recorded by heraldists active in the Partitions of Poland. The morphological pattern parallels surnames like Kowalski, Nowakowski, Lewandowski, and Szymański found in parish registers, Metryka Koronna documents, and migration lists to New York City and Hamburg in the 19th century.

Contemporary distributions are documented in censuses and surname maps for Poland, showing concentrations in the regions of Masovian Voivodeship, Greater Poland Voivodeship, Pomeranian Voivodeship, and historical provinces such as Galicia (Central Europe).

Immigration records list bearers arriving at Ellis Island, settling in urban centers like Chicago, Detroit, Toronto, Melbourne, and São Paulo.
