Iracema combines the Tupi (Brazilian Indigenous) ira (honey) and tembe (lips) — meaning "lips of honey." Iracema is the heroine of José de Alencar's 1865 Brazilian novel Iracema, an Indigenous woman who falls in love with a Portuguese soldier.
Iracema is widely used in Brazil.
Iracema 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 Iracema reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
