Śrīpati (1019–1066) was an Indian astronomer and mathematician, the author of Dhikotidakarana (written in 1039), a work of twenty verses on solar and lunar eclipsesDhruvamanasa (written in 1056), a work of 105 verses on calculating planetary longitudes, eclipses and planetary transitsSiddhantasekhara a major work on astronomy in 19 chapters; and Ganitatilaka, an incomplete arithmetical treatise in 125 verses based on a work by Shridhara.

Śrīpati's father was Nagadeva (sometimes written as Namadeva) and Nagadeva's father, Sripati's paternal grandfather, was Kesava. Śrīpati was a follower of the teaching of Lalla writing on astrology, astronomy and mathematics. His mathematical work was undertaken with applications to astronomy in mind, for example a study of spheres. His work on astronomy was undertaken to provide a basis for his astrology. Śrīpati was the most prominent Indian mathematicians of the 11th century.

Among Śrīpati's works are: Dhikotidakarana written in 1039, a work of twenty verses on solar and lunar eclipses; Dhruvamanasa written in 1056, a work of 105 verses on calculating planetary longitudes, eclipses and planetary transits; Siddhantasekhara a major work on astronomy in 19 chapters; and Ganitatilaka an incomplete arithmetical treatise in 125 verses based on a work by Sridhara.

Genethlialogy was the science of casting nativities and it was the earliest branch of astrology which claimed to be able to predict the course of a person's life based on the positions of the planets and of the signs of the zodiac at the moment the person was born or conceived.
There is one other work on astrology the Daivajnavallabha which some historians claim was written by Śrīpati while other claim that it is the work of Varahamihira. As yet nobody has come up with a definite case to show which of these two is the author, or even whether the author is another astrologer.
Śrīpati had introduced one of the main methods of house division in Jyotiṣa, known as Śrīpati Bhāva System
