Saini is a caste of North India who were traditionally landlords ( zamindars) and farmers. Sainis claim to be descendants of a king, Shurasena, as well as of Krishna and Porus, and to be related to the ancient Shoorsaini clan, noted in Puranic literature. This is disputed and the 1901 census noted that people using the Shoorsaini name were by then found only in Punjab, Haryana, Jammu and Kashmir, Himachal Pradesh and Delhi. Sainis also claim themselves to be Rajputs
As both a statutory agricultural tribe and a designated martial race during the British Raj era that followed the Indian Rebellion of 1857, Sainis had been chiefly engaged in both agriculture and military service since then until recent times. However, since the independence of India, Sainis have diversified into different trades and professions other than military and agriculture. Sainis are now also seen in increasing numbers as businessmen, lawyers, professors, civil servants, engineers, doctors and research scientists, etc.
Sainis profess in both Hinduism and Sikhism. They have a national organization called Saini Rajput Mahasabha located in Delhi, established in 1920.
