Umaswati, also spelled as Umasvati and known as Umaswami, was an Indian scholar, possibly between 2nd-century and 5th-century CE, known for his foundational writings on Jainism. He authored the Jain text Tattvartha Sutra. Umaswati's work was the first Sanskrit language text on Jain philosophy, and is the earliest extant comprehensive Jain philosophy text accepted as authoritative by all four Jain traditions. His text has the same importance in Jainism as Vedanta Sutras and Yogasutras have in Hinduism.
