Muni Tarun Sagar (26 June 1967 – 1 September 2018) was an Indian Digambara monk. His lectures are termed Kadve Pravachan (bitter discourses) because they can be candidly critical of common practices and views. His lectures have been compiled and published in book series also titled Kadve Pravachan. Excerpts from his discourses are often published by newspapers. Unlike most other Digambar Jain monks, his audience often included a majority of non-Jains. His discourses often addressed family or society issues.
