Proviso West High School (PWHS) is a public high school located in Hillside, Illinois, United States. It is a part of Proviso Township High Schools District 209, and was opened in 1958. Its sister schools are Proviso East High School and Proviso Mathematics and Science Academy. The school is located approximately ten miles (16 km) west of metropolitan Chicago in Proviso Township.

The school is less than one mile from the interchange between I-290 and I-88 (referred to locally as the Hillside Strangler). Proviso West High School serves seven villages within the township: Bellwood, Berkeley, Broadview, Hillside, part of Northlake, Stone Park, Westchester, and part of Melrose Park. The current principal is Dr. Albert Brass Jr. Source: Wikipedia (en)
