Upland Unified School District is a school district located in San Bernardino County, California that serves the community of Upland, California. It has a total population of approximately 63,800 and covers a total area of 24 square miles.^[2]

Just prior to the City of Upland's growth spurt in the 1960s, Upland High School was established in 1955. By the 1980s this population growth had the side-effect of overcrowding, which in turn caused students to transfer to other high schools in the Chaffey Joint Union High School District. The affected families then began a movement towards unifying the existing elementary and middle schools into a separate district. Superintendent George Renworth promoted this movement and the Upland Unified School District was established in 1986. Upland High School has been a part of the district since it left the Chaffey Joint Union High School District in 1988.^[3]

The Upland Unified School District is a K-12 district. It has ten elementary schools, two junior high schools, and two high schools. One of the high schools is a continuation school. The district enrolled approximately 11,200 students in the 2007–2008 school year. All of the schools are located in Upland, California.^[4]
