Biju is a popular male name in India, especially in Bengal, Orissa, Kerala, and Bangladesh.
"Biju" is a name derived from the similar rhyming name Viju. It is highly likely that Viju is an affectionate version of the name Vijaya, which means Victory in Sanskrit and several Indian languages. It has a similar meaning in Chinese as well. Biju is associated with Arjuna, the great warrior hero of Mahabharatha. In Kerala, the name Biju is used by all communities: Hindus, Christians, and Muslims, and thus is a secular name, although many have added suffixes which indicate their caste or community.For example BIJU VASUDEVAN PILLAI, in which Biju is the first name and middle name is father's name and the last name is his family name .
This name also may have derived from BIJOU, which is "Jewel" in French - pronounced as Bizhu.
