Tiare is from the Tahitian Tiare — gardenia, flower. Tiare is one of the Tahitian feminine names — central to traditional Tahitian Indigenous Polynesian heritage of Society Islands French Polynesia. Tahitian feminine name reflecting Indigenous Polynesian heritage.
Tiare 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 Tiare reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
