Bajaj was born in Kolkata on June 10, 1938 to Kamalnayan Bajaj and Savitri Bajaj, a Marwari businessman and his wife. Three generations of the Bajaj and Nehru families had a strong tradition of intergenerational friendship. Indira Gandhi and Kamalnayan, Rahul's father, both attended the same school.
