List of deputy chief ministers of Bihar

The Deputy Chief Minister of Bihar is the second highest-ranking member of the state's council of ministers. The current deputy chief ministers of Bihar are Bijendra Prasad Yadav and Vijay Kumar Chaudhary serving in office since 15 April 2026. The position of deputy chief minister is not explicitly defined or mentioned in the Constitution of India. However, the Supreme Court of India has stated that the appointment of deputy chief ministers is not unconstitutional. The court has clarified that a deputy chief minister, for all practical purposes, remains a minister in the council of ministers headed by the chief minister and does not draw a higher salary or perks compared to other ministers.During the absence of the chief minister, the deputy-chief minister may chair cabinet meetings and lead the assembly majority. Various deputy chief ministers have also taken the oath of secrecy in line with the one that chief minister takes. This oath has also sparked controversies.
