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 1900-1904, the school was known as Deerfield High School. The high school served both Deerfield (renamed Moraine in 1998) 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.
