Lysandra is the feminine of Lysander — from the Greek lysis (releasing) and aner (man) — meaning "liberator" or "freer of men." Lysander was the Spartan general who ended the Peloponnesian War.
Lysandra is rare as a given name but rising — chosen by parents drawn to powerful Greek roots.
Lysandra 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 Lysandra reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
