Soriya (សុរិយា) is the Khmer (Cambodian) word for "sun" — from the Sanskrit sūrya. A traditional Cambodian feminine name.
Princess Soriya Roeungsey of Cambodia was the consort of King Norodom Sihanouk.
Soriya 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 Soriya reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
