The '''Bihar Legislature''' (IAST: ''Bihar Vidhan Mandal'') is the supreme legislative body of the Indian state of Bihar. It is a bicameral legislature composed of two houses: the Bihar Legislative Council (Bihar Vidhan Parishad) and the Bihar Legislative Assembly (Bihar Vidhan Sabha).<ref>{{Cite web |title=Bihar Legislature |url=https://www.cpahq.org/directory/bihar/ |access-date=22 November 2024 |website=Commonwealth Parliamentary Association}}</ref><ref>{{Cite book |title=Know Your State Bihar |date=2020 |publisher=Arihant Publication India Limited |isbn=9789313199755 |pages=225 |chapter=Chapter 18: Administrative Set-Up of Bihar |chapter-url=https://www.google.co.uk/books/edition/Know_Your_State_Bihar/0BrzDwAAQBAJ?hl=en&gbpv=1&pg=PA225}}</ref>

The Governor of Bihar, as the constitutional head of the legislature, has the authority to summon and prorogue either house of the legislature and to dissolve the Legislative Assembly. These powers are exercised on the advice of the Chief Minister and the Council of Ministers.

Those elected or nominated to either house of the legislature are collectively referred to as members of the legislature. Members of the Bihar Legislative Assembly are known as Members of the Legislative Assembly (MLAs), while members of the Bihar Legislative Council are known as Members of the Legislative Council (MLCs).

Members of the Bihar Legislative Assembly are directly elected by the people of Bihar from single-member constituencies through the first-past-the-post system. Members of the Bihar Legislative Council are elected indirectly by elected representatives, teachers, graduates and local authorities through the system of proportional representation.

The Bihar Legislature has a sanctioned strength of 243 members in the Legislative Assembly and 75 members in the Legislative Council, including 12 members nominated by the governor from the fields of literature, art, science and social service. The legislature meets at the Bihar State Assembly complex in Patna.
