Pierre Johanns (1 April 1882, Heinerscheid, Luxembourg – 8 February 1955, Arlon, Belgium) was a Luxemburger Jesuit priest, missionary in India and Indologist.
To evaluate his doctoral dissertation on "The Agent Intellect in the Western and Eastern Philosophies," Oxford University could not find suitable examiners, and had to have recourse to Cambridge.
As early as October 1922, he and another Oxford graduate and Jesuit confrere, Georges Dandoy, started The Light of the East, a monthly directed to the Hindu intelligentsia as an instrument of interfaith reflection and dialogue.
In 1938 ill health forced him to go back to Belgium, where he reached the "Indian Juniorate" (founded in 1935) which, until 1971, would train young Jesuits for work in Bengal.
Inspired by the writings of Brahmabandhab Upadhyay (1861–1907), Johanns found in Shankara, the great Hindu Philosopher of the 9th century, spiritual and theological paths leading to Christ.
