Terra Nova High School (sometimes abbreviated to simply TN) is an American public high school in Pacifica in San Mateo County, California, United States. It serves grades 9 through 12 as part of the Jefferson Union High School District.

Terra Nova High School was established in 1961 to serve the growing population in the Linda Mar district of southern Pacifica. Students attended from Vallemar, Rockaway Beach, Mori Point, Fairway, Sharp Park and Pacific Manor districts until Oceana High School was completed the following year.

The 2007 National Book Award finalist Story of a Girl is set at Terra Nova.

The original buildings and campus were designed by Mark Falk & Corwin Booth (of Falk & Booth). The main building originally had only two stories when the school opened in 1961. Portables were added to the rear of the school campus to accommodate the increase in students and need for more classrooms. A major facilities remodel was completed in 1998, and construction of a 400+ seat theater and a new science building began in early 2010 and was completed in 2012.

According to U.S. News & World Report, 62% of Terra Nova's student body is "of color," with 22% of the student body coming from economically disadvantaged households, determined by student eligibility for California's Reduced-price meal program.

In 2011, Terra Nova scored an API of 801, the sixth highest in San Mateo County. By 2013, the last year on record, the school had scored 792, the second highest in the Jefferson Union school district.

The state of California replaced the API system with the California School Dashboard system in 2017, in order to provide "a fuller picture of how districts and schools are addressing the needs of their students while also identifying the specific strengths and areas in need of improvement."

For the school year 2018–2019, Terra Nova scored 6.3 points above the state average in English Language Arts, but 40.4 points below standard in Math. It ranked above average for both Campus Climate - with an annual suspension rate of 5.6% - and Academic Engagement - with a graduation rate (measured by the percentage who received a high school diploma within 4–5 years of entering 9th grade or completed their graduation requirements at an alternative school) of 94.7%.
