Meaning and origin of Sia
Sia is an English name that is usually said to mean “short form of names like Anastasia”.
Sia began as a short form of names ending in -sia, such as Anastasia, whose Greek root means resurrection. Short names like this are common in Europe, and Sia has also come to be used as an independent given name. The singer and songwriter known simply as Sia made the name widely recognized. Because it is so brief, Sia has a bright, modern and minimalist quality, fitting well with other two-letter-sound names such as Mia and Pia. It can stand alone or serve as a nickname for a longer formal name.
Popularity over time
Sia first appears in US Social Security records in 1968. It has never ranked in the national top 1,000, which keeps it genuinely uncommon. It is at its all-time high right now: 2025 brought both its best national rank, #1,107, and its highest count, 215 babies. Use has grown 64% in ten years.
Its national rank moved from #6,263 in 1980, #2,750 in 2010, and #1,107 in 2025. Of the 2,790 US girls named Sia since records began, 40% were born in the 2020s, its biggest decade. The 2010s come next, with 1,026 babies.
Other girls' names that peaked around the same time include Imogen, Ines, Ariela, Sunnie, and Xolani.
