Carlsbad High School is a public high school in Carlsbad, California. First opened in 1957, the high school underwent major redevelopment from 2009 to 2012. In 2010, the API index for the school was 812.

In December 2001, the band No Doubt played a surprise concert at the high school as the first episode of the MTV show "Jammed." Students were not told of the concert until they were dismissed from class for the day. MTV staff worked with school administrators and staff to facilitate the concert between the football field and gymnasium.

Governor Arnold Schwarzenegger visited the high school on August 11, 2006 to announce his plans for the future of funding and education in California's schools.

On February 19, 2016, the band Echosmith played a concert for the school as part of the State Farm #Drive2N2 campaign. The school won the concert as a result of a safe driving video submitted by the broadcasting department to the contest. The broadcasting department received a $100,000 grant for winning.
