On Maharaja Hari Singh Marg along Residency Road in the heart of Jammu city, Delhi Public School Jammu carries the distinction of being the very first branch of the Delhi Public School Society established in Jammu & Kashmir. Founded in 1998 by M.K. Ajastshatru Singh, President of the Rajput Charitable Trust, and his wife Kr. Ritu Singh, the school was built on a vision of making education accessible, meaningful, and aligned with national values. Over the past two and a half decades, it has grown into one of the most consistently recognised names among CBSE schools in Jammu, led currently by Principal Ms. Ruchi Chabra.

Affiliated with the Central Board of Secondary Education and governed by the DPS Society, New Delhi, the school offers classes from Nursery through Class 12. In the 2024–25 board season, students achieved scores up to 97% in both Class 10 and Class 12, continuing a track record of strong results that has earned the school multiple national recognitions — including the Excellence in School Leadership award at the North Educator's Summit in New Delhi, the British Council's International School Award for 2018–21, and the 'Great Legacy in Education (K-12)' award at the Maharashtra Educators Summit in 2019. In 2021, students set a Guinness World Record for the most people assembling a sundial kit during the Indian International Science Festival.

Spread across 11.20 acres, the campus includes science and computer laboratories, a library with over 24,000 books, a 13,924 sq. metre playground, a swimming pool, music rooms, dance rooms, an auditorium, a gymnasium, and an on-campus medical room. The school also runs active NCC and Scouts & Guides units, and offers personality development programmes covering public speaking, leadership, and communication skills from the junior school level onward. Computer Science with C++, SQL and programming is available as an elective at the senior secondary level.
