Lady Irwin School for Girls is an educational institution in New Delhi, India, established in 1927.
The Lady Irwin School for Girls was established in 1927, under the leadership of the late Shri S. R. Das, the Law Member of the Viceroy's Executive Council, for the purpose of making education available under the same roof to all the children of Central Government servants.
The Army Barrack has since been demolished and the middle school is now housed in another building on Canning Lane which was constructed by funds raised by annual PT Shows organized at the National Stadium through the 1960s and 1970s by the students and teachers of Lady Irwin School.
Through the 1960s and 1970s, the Central Board of Secondary Education Merit List was dominated by the students of Lady Irwin School.
The school's motto is Dhiyo yon-ah prachodyath i.e. "Let our faculties flourish in the realization of the Supreme".
