[3] LIU Post is located on 307 acres (1.24 km2) of rolling hills in Brookville, New York, on Long Island's North Shore.

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.

[6] 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.

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 school claimed no responsibility, although residents told the student newspaper they had complained about black outlets shortly before the fire.

Post Residence Life was sued for dismissing a group of residential associations, who made a video exercising their freedom of speech.

Prior to 2019, the university's athletic programs competed at the Division II level.

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.

[18][19] 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.

The athletic fields and courts are used for recreational baseball, football, soccer, softball, and tennis.
