Omji was born on July 14, 1936, to a Brahmin family of princely origin, in Kashmir. They later shifted to Jodhpur, where his father was adopted by the royal family. They were very orthodox and the women in the family had to be behind veils. Even if they fell ill, a doctor could not examine them.
He was the fifth of eight children and theirs was a joint family. Omji graduated in Jodhpur. His elder sister was a professor at the Maharani College in Jaipur. By then his father fell sick so all of them shifted to Jaipur. In Jaipur, Omji did a part-time job in a school. He had also done his first year LLB, but he could not complete it because he was a ring leader in college, always up to some mischief. His attendance was short and he was chucked out.
Om Shivpuri has a daughter, Ritu Shivpuri, who is now an Hindi film actor, and had a son, Vineet. Om Shivpuri died in 1990 of a heart attack. Several of his films were released after his death.
