Angel is from the Greek angelos (messenger) — a 19th-century English shortening of Angela / Angelica. Used as both masculine and feminine; in the United States the feminine usage is more common in English, the masculine more common in Spanish. NCAA national champion at LSU (2023). Angel Olsen (born 1987) — American singer-songwriter. Angel Haze — American rapper. Angel is also the Buffy the Vampire Slayer character Angelus (male).
Angel 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 Angel reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
