Siya is an Indian name, a modern form of Sita, the heroine of the Ramayana and wife of Rama, whose Sanskrit name means "furrow" because she was found in a plowed field; it is one of the most popular girls' names in India today. In the United States it travels easily thanks to its resemblance to Sia and Mia. Siya entered the US top 1000 in 2024 and has climbed to number 879 among girls in 2025, its best rank so far.
