Nanjing International School is a non-profit International school in Xian Lin College and University Town (仙林大学城), Qixia District, Nanjing, enrolling children age 3 to 18 from Pre-Kindergarten to Grade 12.

The school was founded on October 14, 1992, by a small group of expatriate parents who wanted to provide English language education for their children.

After three years of operating in rented rooms at the Nanjing Foreign Language School (NFLS), the enrollment at Nanjing International School grew, requiring more space than the two classrooms at NFLS.

As a result, NIS board members approved the renovation of two buildings belonging to the Dingshan hotel, which were converted into classrooms to accommodate primary/nursery, elementary, and middle school students.
