Protap Chunder Mozoomdar (Bengali: প্রতাপ চন্দ্র মজুমদার Protap Chôndro Mojumdar, also transliterated as Pratap Chander Mozoomdar) (2 Oct 1840–21 May 1905) was a leader of the Hindu reform movement, the Brahmo Samaj, in Bengal, India, and a close follower of Keshub Chandra Sen.

He was a leading exemplar of the interaction between the philosophies and ethics of Hinduism and Christianity, about which he wrote in his book, The Oriental Christ.

Gour Govinda Ray was deputed to examine Hinduism; Aghore Nath Gupta, Buddhism and Girish Chandra Sen, Islam.

[2] It was much discussed in the West, and eventually led to an important correspondence between Mozoomdar and Max Müller about the relationship between Hinduism and Christianity.

[5] The writings of Mazoomdar reflects an outlook that freely acknowledges the value and fundamental affinity of different religions - including Christianity, Islam, or Judaism - and the religious figures associated with their origin and propagation.
