Highland Park High School (HPHS) is a public four-year high school located in Highland Park, Illinois, a North Shore suburb of Chicago, Illinois, in the United States. It is part of Township High School District 113. From 1900 to 1904, the school was known as Deerfield High School. The high school served both Deerfield and Shields townships from 1904 until 1936 and was Deerfield-Shields High School. The building of Lake Forest High School in 1936 provided a school to serve Shields Township students. This led to the return of the name Highland Park High School. A new, separate Deerfield High School opened 20 years later to serve the growing population.
