Manhattan High School is a public high school in Manhattan, Kansas, United States, serving students in grades 9–12. It is part of the Manhattan–Ogden USD 383 school district. For the 2013–2014 school year, Manhattan High had an enrollment of 1,920 students. The school's athletic teams are referred to as the "Indians," and have won 50 state championships.

The first public schoolhouse in Manhattan was built in 1857, serving all grades. The first dedicated secondary school in the town opened in 1873 at the current site of the Manhattan High School "East Campus." The first recorded high school graduation ceremony was held in 1892.

The current East Campus of the school consists of two limestone buildings that are connected by a glass walkway. The first building – on the far right side in the accompanying photo – was opened in 1914 to replace the earlier secondary school. (Many histories date the establishment of Manhattan High from the completion of this building in 1914.) The second building – on the left side of the accompanying photo – was built in 1918 as a separate building for junior high school students (grades 7, 8, and 9).

The West Campus is a red brick building that was constructed in 1956 to be the new high school. Both of the older buildings (the current East Campus) were then utilized for junior high school students. Over the next 40 years, the new high school faced recurring overcrowding issues and was significantly expanded, but the new school simply proved unable to keep up with the town's population growth. After considering and rejecting the idea of building a second high school in Manhattan, in 1996 the town instead built two new middle schools, and moved the ninth grade to the East Campus.

Beginning in 2011, the West Campus underwent a $42.2 million renovation and expansion. The construction added 14 new classrooms, in addition to a number of other improvements, and supplied a new facade for much of the building.

The West Campus is laid out in five parallel hallways, with an open space between each and a central "commons area." Each hallway is lettered from south to north. Classes in the industrial arts are held in a detached building behind the West Campus. A large greenhouse and a new fitness center are also detached from the main building. The West Campus houses two gymnasiums; one is used as a general purpose facility and the other is primarily for basketball and volleyball games.

The East Campus is composed of two three-story limestone buildings, connected with a glass walkway and an annex in the rear (not visible in the above photo), built in 1928. The campus also has a detached gymnasium built behind the main stone buildings.

There are a wide range of learning opportunities offered at MHS, from tutoring for learning-impaired students to dual credit classes at Kansas State University, and a wide range of elective classes. Currently the school offers electives from performing arts to language arts to physical arts. Manhattan High is also the hub of a statewide virtual education academy called the iQ Academy Kansas. The online classes give students the opportunity to study and learn at their own personal pace. 240 students were enrolled in the program as of 2007.

In the 2015–2016 school year there were four National Merit Finalists from Manhattan High.

Manhattan High has teams competing in baseball, basketball (boys and girls), bowling (boys and girls), cross country (boys and girls), football, golf (boys and girls), soccer (boys and girls), softball, swimming & diving (boys and girls), tennis (boys and girls), track & field (boys and girls), volleyball (girls), and wrestling. The school competes at the 6A level (largest schools) in the Centennial League. Manhattan High has its own stadium, Bishop Stadium, which seats 4,000 spectators and hosts football games and track events. The football field was changed from grass to artificial turf in 2013.

The school is a member of the Centennial League, which it joined in 2004. MHS was previously a member of the defunct I-70 League from 1978 to 2004, and before that the Central Kansas League (CKL).

The athletics program has received some national recognition. On June 19, 2007, Sports Illustrated published a list of the top high school athletic programs in each state, and Manhattan High School was declared the top high school athletics program in Kansas for 2007. Also, Manhattan High's football team was nationally ranked in the USA Today poll during the 1987 and 1988 seasons.

Manhattan High's sports teams are called the "Indians." In light of debate over the use of Native American mascots in athletics, the use of the name "Indians" by the high school has been questioned since it was adopted. The mascot name was intended, in part, to honor Frank Prentup, a former football coach of the high school who claimed Indian ancestry. In 2001, the Unified School District 383 Board of Education voted to retain the mascot name but would restrict how the Indian could be portrayed.

In 2015, there was a renewed push to remove the "Indians" name. The following year the Manhattan-Ogden school board voted 7–0 to keep the "Indians" nickname. In addition to honoring the former coach, the other reasons cited by the board for keeping the mascot involved an estimated cost of $300,000 to replace the mascot amidst state level budget cuts. However, the board voted to form a committee that would explore creating a new mascot, determining the associated costs, and finding methods to fund such a change. Additionally, a greater emphasis would now be placed on Native American education at the school and community levels. The committee would report on its findings to the school board by September 2017.
