Lalon (14 October 1772 – 17 October 1890),  also known as Lalon Shah, Lalon Fakir, Shahji and titled Fakir, Shah, was a prominent Bengali spiritual leader, philosopher, mystic poet and social reformer. Regarded as an icon of Bengali culture, he inspired and influenced many philosophers, poets and social thinkers including Rabindranath Tagore, Kazi Nazrul Islam and Allen Ginsberg. Lalon’s philosophy of humanity rejects all distinctions of caste, class, and creed and takes stand against theological conflicts and racism. It denies all worldly affairs in search of the soul and embodied the socially transformative role of sub-continental Bhakti and Sufism.

Lalon founded the institute known as Lalon Akhra in Cheuriya, about 2 kilometres (1.2 mi) from Kushtia railway station. His disciples dwell mostly in Bangladesh and West Bengal. Every year on the occasion of his death anniversary, thousands of his disciples and followers assemble at Lalon Akhra and pay homage to him through celebration and discussion of his songs and philosophy for three days.
