Sia is a short form of Sita, the devoted heroine of the Ramayana.
From Sanskrit ira (इरा), 'the earth; waters; speech', and a name of the goddess of speech and learning (linked to Saraswati). Cross-cultural: Ira is also a Hebrew male name and a Slavic short form of Irina.
Ira is more popular than Sia today: about 222 US babies were given the name Ira in 2025, compared with 215 named Sia.
Sia means Form of Sita (Sanskrit origin), while Ira means the earth; goddess of speech (sanskrit origin).
In US records, Sia first appears in 1968 and Ira in 1880, so Ira has the longer recorded history.
