California State Polytechnic University, Pomona, or Cal Poly Pomona, is a public university located in Pomona, California, United States. It is one of two polytechnics in the 23-member California State University system.

Cal Poly Pomona began as a satellite campus of the California Polytechnic School (today known as Cal Poly San Luis Obispo) in 1938 when a completely equipped school and farm in the city of San Dimas were donated by Charles Voorhis and his son Jerry Voorhis. The satellite campus grew further in 1949 when a horse ranch in the neighboring city of Pomona, which had belonged to Will Keith Kellogg, was acquired from the University of California. Cal Poly Pomona, then known as “Cal Poly Kellogg-Voorhis”, and Cal Poly San Luis Obispo continued operations under a unified administrative control until they became independent from each other in 1966.

Cal Poly Pomona currently offers multiple educational programs in 9 academic units and enrolls over 22,000 students as of fall 2010. The university is one among a small group of polytechnic universities in the United States which tend to be primarily devoted to the instruction of technical arts and applied sciences.

Once known strictly as a commuter school, in recent years Cal Poly Pomona has undertaken an effort to increase its academic standings while also evolving into a more traditional university. The university has raised admissions standards, increased on-campus student residences, built new facilities and expanded its undergraduate research opportunities. Its sports teams are known as the Cal Poly Pomona Broncos and play in the NCAA Division II as part of the California Collegiate Athletic Association (CCAA). The Broncos sponsor 10 varsity sports and have won 14 NCAA national championships.
