Yashovijaya (, 1624–1688), a seventeenth-century Jain philosopher-monk, was a notable Indian philosopher and logician. He was a thinker, prolific writer and commentator who had a strong and lasting influence on Jainism. He was a disciple of Muni Nayavijaya in the lineage of Jain monk Hiravijaya (belonging to the Tapa Gaccha tradition of Svetambara Jains) who influenced the Mughal Emperor Akbar to give up eating meat. He is also known as Yashovijayji with honorifics like Mahopadhyaya or Upadhyaya or Gani.
Early life
Yashovijaya was born in a village called Kanoda in the Mehsana district in Gujarat in 1624 CE. Some sources place his year of birth as 1608 CE. His childhood name was Jasha. He belonged to the endogamous group of Oswal Jains. He lost his father when he was very young and consequently he was brought up by his mother. The inclination towards religious life was inculcated by his mother, who often used to take him to Jain upashrayas. Young Yashovijaya attracted attention of Jain monk Nayavijayaji who was impressed by his impressive memory feat of remembering the Bhaktamara Stotra at a very young age.

Life as a monk
He was initiated as a young monk under the stewardship of Muni Nayavijaya. According to some sources, he came to Varanasi in the company of his teacher Nayavijaya, both having disguised themselves as Brahmins to get into the matha. By some accounts, he was sent by his guru to Varanasi to study logic and philosophy along with another disciple Vinayvijaya. Other sources indicate, he had gone to Varanasi on his own in 1626, disguised as a Brahmin. By around 1638 he confessed that he was a Jain monk and was at once asked to leave the matha. But the sources are unanimous that for around 12 years he studied Sanskrit, Prakrit, logic and Metaphysics. He became skilled in the field of Navya-Nyāya branch of logic and thus earned the titles Upajjhaya (teacher), Nyayavisharada (one who is skilled in logic) and Nyayacarya (authority on logic).

According to Jonardon Ganeri, Yashovijaya's intellectual biography can be seen as falling under three heads: an apprenticeship in Varanasi studying Navyanyaya, a period writing Jaina philosophical treatises using the techniques and methods of Navyanyaya, and a time spent writing works with a markedly spiritual and religious orientation. One of the decisive events in the process leading to this transformation was Yashovijaya's meeting with Anandghan, a Jain spiritual poet and monk.

He was a prolific writer and is said to have authored around 100 works in Sanskrit and Gujarati. After a career as a monk, philosopher, author, poet and logician, for almost 80 years, he died at Dabhoi, Gujarat in 1688 CE.
Philosophy
Paul Dundas calls Yashovijaya as the last truly great intellectual figure in Jainism, who rose to fame on account of his learning and mastery of sophisticated logical techniques as well for his interest of mysticism in later life. Yashovijaya often refers to the 8th Century Jain scholar-monk Acarya Haribhadra in his works, indicating that he saw himself as Haribhadra's successor. Haribhadra's reputation for being influenced only by the logical cogency of the doctrines and viewpoints (anekantavada) ultimately shaped Yashovijayas irenic but sometimes critical attitude towards other sects and traditions. Yashovijaya had not only studied all the great Svetambara authors from the oldest to the latest, he was also well read in important Digambara works. He wrote several important Navyanyaya works on Digambara Nyaya texts such as the Aptamimamsa of Acarya Samantabhadra. The Jain tradition is remarkably ecumenical when it comes to Nyaya and Acaryas of both the Digambara and the Shvetambara traditions have composed texts in the genre of Nyaya and the texts are read by monks and scholars of both traditions. Furthermore, Yashovijaya he was well versed in philosophy of diverse schools such as Vedantic, Sankhya, Yoga, Mimāṃsā and Buddhist.
