Ahe Dayamaya Biswa Bihari is a poem in the Oriya language, by the Oriya writer Ramakrushna Nanda.
The poem was reportedly a favourite of Mahatma Gandhi while he was at Sabarmati ashram. This song was included in his Oriya text book Sahitya Sopana, and went on to become the most popular song in Orissa due to its simplicity and beauty.
In 2009, a controversial version of the poem was circulated in Orissa on cassette tape, with angry reactions from fans of the poem[1].
