Granada Hills Charter (often abbreviated to GHCHS/GHC or simply Granada), formerly Granada Hills High School, is an independent charter school consisting of almost 6,000 students in grades K–12, located in the Granada Hills neighborhood of Los Angeles, California, United States. It is affiliated with the Los Angeles Unified School District (LAUSD).

Granada also, as of 2011, has a high Academic Performance Index (API) score of 878, greatly exceeding the target API score of 800 for all schools in California. On April 12, 2011, Granada was named a 2011 California Distinguished School. On December 22, 2011, Granada became an International Baccalaureate World School. Since 2011, the school has won seven National Academic Decathlon Championships.

Granada Hills High School is a comprehensive public high school, founded in 1960. Bryce Schurr was the first acting principal of the school. It was in the Los Angeles City High School District until 1961, when it merged into LAUSD.

In the 1970–71 and 1971–72 school years, Granada Hills High had the largest student body of any high school in the United States. Overcrowding at the school was relieved with the 1971 opening of John F. Kennedy High School.

In 1994, the school opened a LAUSD magnet school with emphasis in math, science and technology in conjunction with the California State University, Northridge. In 2003, the school was awarded charter status which granted it fiscal and instructional autonomy.

In 2003, the Los Angeles Board of Education voted to allow the school to become a charter, making it the largest school in the United States to convert to a charter school. The school administration asked for a charter status since being directly operated by the district limited its fundraising opportunities, and it also was against LAUSD funding cuts.

In mid-2013, Granada Hills Charter High School purchased the nearby Pinecrest Northridge Elementary School campus for $5.6M, using funds obtained from the American Recovery and Reinvestment Act of 2009. Granada Hills Charter High School used this new land to create iGranada, a campus specializing in digital arts and sciences. This campus opened for the first time for the Fall 2015 school year.

As part of their Charter Renewal Petition, GHCHS has applied to increase their enrollment from 4,300 students up to 5,500 students. This includes adding approximately 200 additional grades 9–12 seats to the existing GHCHS campus, through a Charter Augmentation Grant, and adding up to 1,000 additional seats at the Pinecrest site (or at another possible property acquisition).

In 2020 the grade span changed to K–12.

On campus, there are six computer labs, each with more than 35 computers. There are also laptop carts, which house many laptop computers and can be transported around the campus for enrichment activities. Science classrooms are updated with new lab technology often. Most classrooms have Smart Boards and projectors, increasing the overall student interaction in class.

Beginning in the 2015–2016 school year, Chromebooks are given to every student. Teachers may use Canvas (or Google Classroom prior to 2022) to post assignments, online teaching materials, and give instant feedback to the students. Additionally, the school has wifi networks campuswide, and can provide wifi at a student's home if they cannot afford it.
