Jaishanaa is a feminine given name of Hindu origin, formed from Sanskrit components. The element jaya denotes ‘victory’ or ‘conquest’, while shāna (or śāna) conveys the idea of a radiant ray or brilliance.
The compound therefore conveys the literal sense of a victorious or shining ray. The name is found mainly in India among speakers of Hindi and related languages and is used for girls.
It does not appear in classical literary texts but follows a common pattern of Sanskrit-based modern Indian names that blend positive lexical roots. Its usage remains relatively limited.
