Janoušek

Janoušek is a Czech surname. It is a relatively common surname in the Czech Republic. The origin of the name is likely derived from the given name Jan (John), a popular given name of Hebrew origin meaning "God is gracious," with the suffix "-oušek" functioning as a diminutive or endearment. Therefore, Janoušek can be interpreted as "little Jan" or "dear Jan's [relative]".

Like other Czech surnames, its use is generally governed by grammatical rules regarding gender; traditionally, female descendants would have a slightly different surname form (Janoušková).
