LIU Post, formally the C. W. Post Campus of Long Island University and often referred to as C. W. Post, is a private university in Brookville, New York, on Long Island. It is part of Long Island University (LIU), and the largest university in the LIU system.

The campus is named after C. W. Post, father of Marjorie Merriweather Post, who sold her Long Island estate known as Hillwood to Long Island University in 1951 for $200,000 ($2,347,692 today). Three years after acquiring the property, LIU renamed it C. W. Post College in honor of Post's father.

LIU Post is located on 307 acres (1.24 km) of rolling hills in Brookville, New York, on Long Island's North Shore. The area is sometimes datelined as Greenvale, because there is no "Brookville" post office, and the school is in the zip code that is served by the Greenvale post office, which is to the west. Greenvale station is the nearest Long Island Rail Road station.

Humanities Hall and Life Sciences/Pell Hall are the main educational buildings on campus, and house most of the core curriculum classes. Classes are also held in Hoxie Hall, Roth Hall, Lorber Hall, the Theater Film and Dance building, Sculpture Studio, Crafts Center, Fine Arts Center, B. Davis Schwartz Memorial Library, and the Kahn Discovery Center.

The Tilles Center for the Performing Arts is on the west side of the campus. Previously known as the Bush-Brown Concert Theater (named for the longtime Long Island University chancellor Dr. Albert Bush-Brown), the Tilles Center has hosted many musical and theatrical events.

The Hillwood Commons serves as the student activities center, and also has several administrative offices, including financial aid and bursars office, as well as the Promise office which handles all student day-to-day activities (classes, student organizations, housing, etc). Hillwood has a study lounge, commuter lounge, recreation lounge, and TV lounge (located on opposite sides of the two-story building) that are open as long as Hillwood is open. The Hillwood Cafe, Subway, and Starbucks are all located here and serve as the main dining areas, along with the Winnick Student Center serving as the single dining hall on campus for residential students.

The Hillwood Commons serves as a meeting area for resident and commuter students to get to know each other through informal association outside of the classroom. The Hillwood Commons area also houses the Campus Concierge, Hillwood Computer Lab, Hillwood Cinema, School Bookstore, and multiple student run businesses, such as Browse (electronics store), The Student Body Collective (Clothing boutique), and Sharknation (merchandise shop).

The university's C. W. Post Interfaith Chapel is home of the Interfaith Center, which provides both religious services as well as partnerships with community organizations. The chapel was first conceived in 1968 by Bradley Delehanty and completed by the noted Long Island architectural firm Alfred Shaknis and Peter S. van Bloem in the classic Jeffersonian style Georgian architecture design as a tribute to all religious faiths. Included among its notable architectural features are a domed rotunda at the main sanctuary, as well as soaring Doric columns at the main entrance which call to mind the ancient Roman Pantheon.

Students may live in one of the eight residence halls on campus. All are co-ed with males and females divided by floor or wing. Each hall accommodates from 40 to 380 students. Suffolk, Kings, Queens, and Nassau Halls form the "Freshman Quad"/ and all first year students residing on campus are required to dorm in these buildings.

The South Residence Complex, also known as the Suites, feature an all-suite design with up to eight students sharing a common living area, double bedrooms, and a semi-private bath area. Every residence hall has lounges for relaxation or study and laundry facilities.

The weekly student newspaper, The Pioneer, has reported that many of the dorms are poorly maintained by students. In 2007, a dorm room in Riggs Hall was completely scorched by an electrical fire. Students were not in the room at the time, but their belongings were destroyed. The school claimed no responsibility, although residents told the student newspaper they had complained about black outlets shortly before the fire.

In 2006, C.W. Post Residence Life was sued for dismissing a group of residential associations, who made a video exercising their freedom of speech. The students retained an attorney in their defense, and the university agreed to pay their legal fees if the students dropped the lawsuit and signed a non-disclosure agreement.

In January 2012, Long Island University rebranded itself as LIU. A simplified logo was introduced, replacing the Long Island map and the words "Long Island University" with the bold letters "LIU" and a triangle. The logo's upward triangle, the Greek symbol of delta, symbolizes upward movement and change. The names of LIU's six campuses also received shorter designations, uniting them under the new LIU brand. The C.W. Post Campus of Long Island University became known as LIU Post.

LIU Post is registered with the New York State Education Department and accredited by the Commission of Higher Education of the Middle States Association of Colleges and Secondary Schools. Various academic programs are specially accredited by professional organizations. Organizations that professionally accredit LIU Post programs include:

LIU Post is located about 25 miles (40 km) east from New York City, the nation's largest city. Students can participate in various clubs, organizations, and student leadership opportunities.

Students at the university predominantly come from eastern Long Island, New York City, and the New York metropolitan area, and there are a smaller number of students from elsewhere in the nation and from foreign nations.

The university has eight Greek Life organizations on campus: Alpha Epsilon Phi, Alpha Xi Delta, Delta Zeta, Kappa Kappa Gamma, Phi Sigma Kappa, Sigma Alpha Epsilon, Sigma Delta Tau, and Tau Kappa Epsilon.

Long Island University's athletic programs are the LIU Sharks. They compete in the National Collegiate Athletic Association at the Division I level, the highest level of collegiate athletics. Prior to 2019, the university's athletic programs competed at the Division II level. The programs are governed by the NCAA, the Eastern College Athletic Conference (ECAC), the East Coast Conference (ECC), and the Northeast-10 Conference (NE-10). Prior to 2019, the two LIU campuses had two athletics teams, C.W. Post had the LIU Post Pioneers, and competed in Division II. The LIU campus in Brooklyn competed at the Division I level as the Blackbirds.

In July 2019, the two campuses merged their two athletics teams into a single unit competing in Division I, and assumed the name LIU Sharks.

In addition to its NCAA-sanctioned athletic programs, students may participate in various sports, including basketball, racquetball, swimming, and volleyball, for leisure at the Pratt Recreation Center. There is a fitness center for aerobic and cardiovascular workouts on the campus. The athletic fields and courts are used for recreational baseball, football, soccer, softball, and tennis.

The Pratt Center also serves as one of the Nassau County venues for New York State high school boys and girls basketball playoff games.
