Raghuvanshi (or Raghuwanshi) (Sanskrit: रघुवंशी) is an Indian dynasty, first mentioned in the Indian mythology. Raghuvanshi is believed to be a lineage of kings tracing its ancestry to Surya. Raghuvanshi kings like Mandhata, Harishchandra, Sagara, Bhagiratha, Dilīpa, Raghu, Aja, Dasaratha and Rama.
The clan founder was Vivasvan or Vaivaswat Manu who was also known as Arka-tanaya or son of Arka (Surya), is supposed to have lived coeval with the origin of the world. The name Vivaswan literally means "master of the rays"; the sun, or sun-god. The first historically significant king of this dynasty was Vivaswan's grandson Ikshvaku, so the dynasty is also known as the Ikshvaku dynasty. Raja Prithu was son of Ikshvaku. Because of the greatness of Raja Prithu, whole world was known as Prithvi ("Earth").
- Mandhata, who is said to have ruled the entire earth during the Vedic era, and defeated the Indra-head of Devtas.
- Harishchandra, the king of Ayodhya, believed to be an exemplar of honesty
- Sagara, a king who was tricked by Indra into a conflict with the sage Kapila, leading to the death of his 60,000 sons, the descent of the Ganges to earth, and his sons' revival
- Bhagiratha - Sagara's great-grandson, after strenuous penances, at last succeeded in bringing Ganges down from Heaven. When she flowed over the remains of his ancestors, their souls were redeemed, and the ocean was refilled. Ganges also bears the name "Bhagirathi", in honour of his deed.
