Kaczmarek is the 18th most common surname in Poland, with over 62,000 bearers as of 2009, and it is especially prevalent in Greater Poland and Lubusz Land. The name derives from the Old Polish word karczmarz, meaning "innkeeper," and its diminutive suffix -ek gives Kaczmarek the sense of "son of the innkeeper" or "little innkeeper." The base karczma ("inn") itself is a loanword, ultimately from the Old Czech krčma, which may be of Germanic origin. Variants and Related NamesThe standard Polish form Kaczmarek contrasts with the phonetically derived variant Karczmarek, both sharing the same root. Unlike patronymic surnames ending in -ski, this occupational name uses a common nickname-style ending. The archaic feminine form Kaczmarkowa referred to the wife of an innkeeper, while the plural Kaczmarkowie denoted the family. Notable BearersNotable individuals with the surname include:Jan A. P.
