Meaning & Definition

At its core, “Katz” is primarily known as a surname, but its meaning is multi-layered:

• Primary Meaning (Surname): In many cases, Katz is an acronym of the Hebrew phrase Kohen Tzedek, where Kohen means “priest” and Tzedek means “righteousness” or “justice.” This suggests a link to the Jewish priestly class (Cohanim). Wikipedia+2Forebears+2
• Secondary Meaning (Germanic): Katz can also be a nickname derived from the German word Katze, meaning “cat.” Geneanet+1

Background & Origin

The origin of “Katz” has historic and linguistic depth:

• The Hebrew-acronym theory holds strong: Kohen Tzedek (כהן צדק) literally means “priest of righteousness,” and the initial letters ק (Kaf) and צ (Tzaddi) form the abbreviation כ״ץ, read in Latin characters as “Katz.” Beth Shalom+1
• Historically, Jewish families adopted surnames fairly late (relative to other groups). “Katz” as a hereditary family name appears in records around the 17th century. Forebears+1
• There’s also a Germanic lineage: in some cases, Katz evolved from “Katze” (cat) as a nickname or descriptive surname. The Meaning of Names+1
• Another historical note involves Katzenelnbogen, a region in Germany. Some branches of the family shortened “Katzenelnbogen” to Katz over time. jewishpress.com+1
• The Jewish Press also notes that not every Katz is necessarily a Kohen — over time, the name was adopted more broadly, and not all bearers are of priestly descent. jewishpress.com
