Jagannatha Das Babaji (IAST: Jagannātha dāsa Bābājī; 1776–1894) was an influential leader (guru) in the Gaudiya Vaishnava tradition of Hinduism, respected as a Mahātmā (saint) by followers of his lineage. He accepted initiation (diksha) from Jagadananda Goswami of Vrindavan, and later accepted babaji initiation (Vaishnava sannyasa) from Madhusudana dasa Babaji. For the rest of his life, his example as a Gaudiya Vaishnava devotee was an inspiration to many in the community. Bhaktivinoda Thakur is quoted calling him "the commanding chief of the devotees".
