Jagadguru, literally meaning "guru of the universe", is a title used in Sanātana Dharma. Traditionally, it has been bestowed upon or used for ācāryas belonging to the Vedānta school (among the six traditional schools of thought in Hinduism) who have written Sanskrit commentaries on the Prasthānatrayī (literally, 'the three sources') – the Brahma sūtras (the original scripture of Vedānta), the Bhagavad-gītā (part of the Mahābhārata) and the principal Upaniṣads.

Jagadguru is also honoured as the title by Kashi Vidvat Parishat in Varanasi for the knowledge and value of particular guru. The title "Jagadguru Ramanandacharya" is used in the lineage of Ramananda, founder of Ramanandi Sampradaya.
