The Nassau Veterans Memorial Coliseum, more commonly known as the Nassau Coliseum, and branded as NYCB Live: Home of the Nassau Veterans Memorial Coliseum for naming rights reasons, is a multi-purpose indoor arena in Uniondale, New York, east of New York City. The Coliseum is approximately 7 miles (11 km) east of the eastern limits of the Borough of Queens of New York City, and is located next to the Meadowbrook Parkway.
Opened in 1972, the Coliseum occupies 63 acres (25 ha) of Mitchel Field, a former Army airfield, later an Air Force base. The facility is located in the Town of Hempstead, within the Uniondale 11553 ZIP code. The Coliseum is used for sporting events, concerts, large exhibitions and shows as well as trade shows—44,000 square feet (4,100 m2) at the main arena, 60,000 at the Expo Center. In 2015, the arena was temporarily closed for a major renovation which was completed in April 2017.
The New York Islanders of the National Hockey League (NHL) played at the Coliseum from 1972 to 2015 before moving to Brooklyn's Barclays Center. After the move proved to be commercially unsuccessful, the team began splitting its home schedule between Barclays and the renovated Coliseum in 2018, and will do so until at least 2021 after the completion of its new Belmont Park Arena. It was the former home of the New York Nets of the American Basketball Association (ABA) and National Basketball Association (which now plays at Barclays as the Brooklyn Nets) from 1972 to 1977. In 2017, the venue became the new home of the Brooklyn Nets' NBA G League team, the Long Island Nets.
