The Solar dynasty or Sūryavanśha (lit. 'Descendants of the Sun'; Sanskrit: सूर्यवंश), also called the Ikshvaku dynasty, is a lineage or dynasty said to have been founded by Ikshvaku. In Hindu literature, it ruled the Kosala Kingdom, with its capital at Ayodhya, and later at Shravasti. They worshipped their clan deity, Surya (a Hindu solar deity), after whom the dynasty is named. Along with the Lunar dynasty, the Solar dynasty comprises one of the main lineages in Hinduism.
According to Jain literature, the first Tirthankara of Jainism, Rishabhanatha himself, was King Ikshvaku. Twenty-one further Tirthankaras were born in this dynasty.
