Established in July 1909, Patna Law College emerged as a distinguished institution dedicated solely to legal education. Before its founding, legal studies were conducted at Patna College. Initially affiliated with Calcutta University until 1917, the college seamlessly transitioned its affiliation to Patna University upon its establishment that year. Until January 1, 1952, Patna Law College operated as a government institution, functioning independently. Subsequently, it gained status as a constituent college of Patna University under the Patna University Act of 1951.

This centre of higher education has a rich legacy, having produced notable legal luminaries such as two Chief Justices of India, Mr. Justice B.P. Sinha and Mr. Justice L.M. Sharma, and the First Attorney General of India from Bihar, Sri Lal Narain Sinha. Its alumni also include a multitude of Supreme Court and High Court judges, esteemed jurists, accomplished advocates, renowned academicians, and proficient administrators, all occupying prestigious positions across various domains.
In the political sphere, Patna Law College has made significant contributions, with prominent alumni like Sri Lalu Prasad Yadav, former Chief Minister of Bihar, Sri Sushil Kumar Modi, former Deputy Chief Minister of Bihar and Mr. Ravishankar Prasad, former Law Minister of India.
Enjoying permanent affiliation with the Bar Council of India, the college adheres to updated syllabi prescribed for its Three-year Law Course leading to an LL. B Degree from Patna University. Upon successful completion of the six-semester Law Examinations conducted by the Patna University Examination Section in three parts (LL.B. Part I, Part II, and Part III), students are awarded their Law Degree.
Drawing talented students and faculty from across Bihar and India, Patna Law College stands as an emblem of excellence and integrity in legal education.
