Tamar (תָּמָר) comes from the Hebrew word for "date palm" — the tall, slender, fruit-bearing tree that has been central to Middle Eastern agriculture and poetry for millennia.
Tamar is among the most popular girl names in Israel today. It is rising in Western records, sitting in the U.S. top 800 and climbing. The Georgian Queen Tamar (1184-1213) is also a famous bearer.
Tamar 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 Tamar reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
