International Indian School Riyadh (Arabic: المدرسة الهنديه العالمية بالرياض), formerly the Embassy of India School, Riyadh is a K–12 English-medium community-based foreign school in Riyadh, Saudi Arabia, run by the Indian embassy. Established in 1982 with assistance from then Indian prime minister Indira Gandhi, it was the first community-based institute in which was established to primarily serve the Indian diaspora in the country. It offers curriculum prescribed by the Central Board of Secondary Education and is approved by the Ministry of Education, Government of Saudi Arabia.

In the wake of a sudden and exponential influx of Indian workers and professionals in Saudi Arabia as a consequence of the 1973 energy crisis and subsequent oil boom, the new generation of expatriate families in the country struggled to provide their children with quality-education as the British and American schools were costly enough get enrolled, and thus, infeasible. Zeenat Musarrat Jafri, an Indian educator from Lucknow and a former teacher at Kendriya Vidyalaya who had arrived in Riyadh in 1979 with her husband, also faced similar hurdles in enrolling her three-year-old son into a proper school. She soon realized the importance of a community-based school in the country and reached out to the-then Indian prime minister Indira Gandhi during her four-day state-visit to Saudi Arabia in April 1982 and asked her to speak to the Saudi authorities to get a permission for the school. The school was founded on 9 October 1982 as Embassy of India School, Riyadh with just 20 students to cater to the educational requirements of the children of Indian expatriate community working in and around Riyadh city.
