Tova (טוֹבָה) is the feminine of Tov (טוֹב), the Hebrew word for "good." In Genesis 1, after creating each part of the world, God says "ki tov" — "it is good" — and after creating humans says "tov me'od" — "very good." The name carries that primordial blessing.
Tova is widely used in modern Israel and across the Jewish diaspora. The Yiddish variant Toby is more common in English-speaking Jewish families.
Tova does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Tova reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
