Mahakavi Krittibas Ojha^[1] (Bengali pronunciation: [ˈkrit̪ːiˌbaˑs ojʰa]; 1381–1461) was a medieval Bengali poet. His major contribution to Bengali literature and culture was Indian epic Rāmāyaṇa in Bengali. His work, the Śrīrām Pā̃cālī,^[1] is popularly known as the Krittivasi Ramayan. His work, edited by Jaygopal Tarkalankar, was published by the Serampore Mission Press.^[1]

Krittibas Ojha was born in a Brahmin family at Phulia village of modern-day Nadia district in the Indian state of Paschimbanga (West Bengal).^[2] He was the eldest among his father Banamali Ojha's six sons and one daughter.

The word "Krittibas" is an epithet of Hindu god Shiva. It is known that when Krittibas was born, his grandfather Murari Ojha was preparing for a pilgrimage to Chandaneswar in Odisha, hence the child was named after Shiva, the predominant deity of the nearest Odisha pilgrimage to Bengal. At the age of 11, Krittibas was sent to North Bengal (in other opinion, to Nabadwip) for higher studies. After finishing studies he was traditionally honoured by the King of Gauda himself by the offerings of a garland, some sandal water and a silk scarf. Upon returning to his home at Phulia, he translated the Valmiki Ramayana epic & The original Mahabharata epic into Bengali(Sadhu bhasha or Sanskritised Bengali)/.^[3] Kritibas Ojha himself later transcipted the Sadhu bhasha or Sanskritised Bengali version of Valmiki Ramayana epic in Chalit bhasha or Simple Bengali version. later on in the 1930s Kazi Nazrul Islam transcipted Sadhu bhasha or Sanskritised Bengali version of Mahabharata epic in Chalit bhasha or Simple Bengali version.
