Herbert Hoover High School, usually referred to simply as Hoover High School or Hoover, is a public secondary school located on the Northwest side of Des Moines, Iowa.

It is one of five secondary schools under the district of the Des Moines Independent Community School District, and was named after Iowa native and the 31st United States president Herbert Hoover. The school's athletic teams are called the Huskies and compete in the Iowa Alliance Conference. In 2017, Hoover High reached half a century of existence.

As of the 2022-23 school year, there were nearly 1,000 students enrolled at Hoover. Hoover has one of the most diverse student bodies of any high school in Iowa, having students that derive from dozens of countries. The secondary school typically has a graduating class of about 200 students a year.

Former Iowa governor Chet Culver was an instructor and sports coach at Hoover High School in the 1990s before running for Secretary of State of Iowa. Timm Pilcher is the adviser for the internationally award-winning newspaper, The Challenger, and also performs in the band Faculty Lounge. Emily Griffin is the current Theater Arts and Play Production instructor. The auditorium was named after former theater teacher Denis Hildreth in 2008, who taught at the school for almost 25 years. In 2003, Hildreth was inducted into the Iowa High School Speech Association Hall of Fame. The current principal is Qynne Kelly. The music director is Randall E. Hoepker, who is also the band director. Under him in the music department is Lisa Fried (orchestra) and Alexander Fitzgerald (choir). The head of the science department is currently Eric Hall, who in 2013 won the Rotary Club of Des Moines Teacher of the Year award for his efforts in the field.

Hoover competes as a school in the Iowa High School Athletic Association 4A school system. It is a member of the Iowa Alliance Conference, along with all four of the other DMPS high schools and Ottumwa High School. Hoover's primary rival is Des Moines Roosevelt. The two schools compete in both academics and athletics alike. However, other rivals include but are not limited to Des Moines North, Johnston High School, and Urbandale High School.

Hoover High School's boys' basketball team was undefeated and won the state championship in the 2005-2006 school year. They also won the sportsmanship award at the conclusion of the tournament.

The school's stadium was built in the mid-'90s and named after former Hoover student, Cara McGrane, who was tragically murdered on November 29, 1992. In 2015, the field was dedicated and named after former athletic director, Dan McClanahan. McClanahan was also inducted into the Iowa Football Coaches Hall of Fame in 1998, and served as Hoover's AD from 1999-2010.

Unlike the rest of the school's sports teams, the girls' swimming team is known as the Marlins; when the school opened in 1967, the team decided they wanted to be different, and the alternate name was born and used to this day.

Wednesday, October 1, 2014, long-time governor Terry Branstad signed a proclamation in Hoover's library declaring the month of October as College Application Month in Iowa.

Beginning in the 2008-2009 school year, Hoover began block scheduling. Each day includes four blocks approximately 80 minutes in length. This allows for a longer teaching time and also for the students to receive a 45-minute lunch. The days are split into alternating green and gold days, which alternate every other day for a total of eight classes every two days. Many students also attend Central Academy and Central Campus in downtown Des Moines in order to acquire college credit and technical proficiency. In 2014, Hoover became an International Baccalaureate world school, and also consistently ranks within the top 50 in the state of Iowa's AP Index compiled by the University of Iowa. Additionally, Hoover has been awarded a grant from the Governor’s STEM Advisory Council to enhance several programs. In 2015, Hoover was awarded the STEM BEST grant for the South Central region by the Governor’s STEM Advisory Council to further establish educational opportunities for students. Earlier in the year, World Food Prize speakers also came to lecture and engage students as well.

Students are required to take at least three years of all core classes. PE is only required for four semesters. Additionally, a number of electives are available for students within the curriculum. The district annually decides how many credits a student must earn to graduate.
