The sacred Hebrew name of God meaning 'I am who I am,' derived from the Tetragrammaton YHWH.
Yahweh is the most sacred name in the Abrahamic religious tradition — the personal name of the God of Israel, represented in the Hebrew Bible by the four consonants YHWH (יהוה), known as the Tetragrammaton. Its etymology connects to the Hebrew verb *hayah* (הָיָה), 'to be,' making the name a first-person declaration: 'I AM' or 'I AM WHO I AM' — the name God reveals to Moses at the burning bush in Exodus 3:14. This self-referential name encodes the concept of absolute, self-existent being: the one who exists by necessity rather than contingency.
In Jewish tradition, the name is considered so holy that it is never pronounced; instead, readers substitute Adonai ('my Lord') or HaShem ('the Name'). This practice of reverential avoidance dates at least to the Second Temple period. In Christian traditions, the name appears in scholarly and liturgical contexts, and in some Protestant hymns ('Guide Me, O Thou Great Jehovah').
The Greek translation of YHWH as Kyrios ('Lord') shaped the entire Greek New Testament. Academic reconstructions of the original pronunciation — Yahweh — are scholarly conventions, not sacred usage. As a given name for a child, Yahweh stands entirely apart from every other name on this list.
It would be considered deeply inappropriate or outright blasphemous in Jewish, Christian, and Islamic traditions, and would almost certainly face legal challenges in countries like Germany, New Zealand, or Iceland that restrict names deemed offensive or burdensome. Its appearance in contemporary baby name databases is vanishingly rare and represents extreme parental idiosyncrasy rather than a naming trend. The weight of the name — three thousand years of the most intense theological reverence in Western history — makes it categorically unlike any human name.
