Kfir (sometimes spelled Kefir) is a Hebrew given name meaning "lion cub." The word kfir (כְּפִיר) appears in the Hebrew Bible, notably in passages such as Judges 14:5 where a young lion is described, and in the poetic books of the Old Testament (e.g., Psalm 104:21, Amos 3:4). The name symbolizes strength, courage, and ferocity, qualities associated with the king of beasts. As a personal name, Kfir gained popularity in modern Israel, particularly after the establishment of the state, reflecting a broader trend of using animal names (such as Ari for “lion”).Linguistically, the root k-p-r (כ־פ־ר) is related to covering or atoning in Semitic languages, but in the context of Kfir, it specifically refers to the young lion. The name is unisex in theory but predominantly masculine. Its resemblance to the fermented dairy drink “kefir” is coincidental; the beverage name is of different origin.Cultural references include the Israel Aircraft Industries Kfir fighter jet, named after the animal to evoke speed and power. Notable bearers of the name include Israeli footballer Kfir Eisenberg.Meaning: Lion cubOrigin: HebrewType: First nameUsage: Israeli, Hebrew-speaking communitiesDirectly related: Ari
