Beyoncé is from her mother Tina's maiden name Beyincé — a Louisiana Creole surname of uncertain origin (possibly French bien aimé, "well loved," or West African). Her 2018 Coachella headlining performance — "Beychella" — was the first by a Black woman in the festival's history.
Beyoncé 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 Beyoncé reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
