Langat Singh College, popularly known as L. S. College, is the premier and oldest institution of higher education in North Bihar. Established in 1899, the college has made a lasting contribution to the educational, literary, social, and political development of the region. Over the decades, it has earned a reputation for academic excellence and has produced numerous distinguished alumni.

The college was founded during the rise of Indian nationalism, a period marked by growing awareness of education as a tool for social progress and national development. Its establishment was made possible through the collective efforts and generous support of the local community, reflecting their commitment to promoting higher education in North Bihar.

Among the key figures behind the institution's foundation, Babu Langat Singh played the most significant role. His vision, dedication, and philanthropic contributions were instrumental in establishing the college, which was later named in his honor as a tribute to his invaluable service.
