Maxine is the French feminine of Max — from the Latin maximus, meaning "greatest." The name was popularised in the 1930s by the Andrews Sisters' Maxene Andrews.
Maxine peaked at #56 in 1932. Today Maxine is returning fast — currently in the U.S. top 700 and climbing.
Maxine 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 Maxine reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
