'''Govindasvāmi''' (or '''Govindasvāmin''', '''Govindaswami''') (c. 800 – c. 860) was an Indian [[mathematical]] [[astronomer]] most famous for his ''Bhashya'', a commentary on the ''Mahābhāskarīya'' of [[Bhāskara I]], written around 830. The commentary contains many examples illustrating the use of a [[Sanskrit]] [[place-value system]] and the construction of a [[sine]] table.<ref name="MacTutor">{{MacTutor Biography|id=Govindasvami|title=Govindasvami}}</ref>

His works have been quoted extensively by [[Sankaranarayana]] (fl. 869), [[Udayadivākara|Udayadivakara]] (fl. 1073) and [[Nilakantha Somayaji]] (c. 1444-1544). Sankaranarayana was the director of the observatory founded in [[Kodungalloor|Mahodayapuram]], the capital of the [[Chera Perumals of Makotai|Chera kingdom]], and is believed to be the student of Govindasvami. In his book, [[Sankaranarayana]] gives explanations to the insightful questions of the king [[Sthanu Ravi Varma|Ravi Varma]], then ruler of Mahodayapuram and from these references the period of [[Sankaranarayana]]  is known.{{cn|date=January 2023}}

His work ''Govindakriti'' was a sequel to [[Āryabhaṭīya]] and is lost. Other works attributed to Govindasvami include''Govinda-paddhati'' (on astrology) and ''Ganita-mukha'' (on mathematics). Like ''Govinda-kriti'', these are lost, and known only from mentions and quotations by later writers such as Sankaranarayana and Udayadivakara.<ref>{{cite book |editor=William E.
