Uniondale is a hamlet and census-designated place in Nassau County, New York, on Long Island, in the town of Hempstead. The population was 32,473 at the time of the 2020 census. Uniondale is home to Hofstra University's north campus, as well as a portion of its southern campus.
The community unsuccessfully tried incorporating itself as a village in the 1970s.
In the early 1970s, several Uniondale residents attempted to incorporate their hamlet as a village, citing dissatisfaction with the way their community was being represented on the board of the committee for redeveloping Mitchel Field, regarding matters like policies and the plans.[3] Their incorporation plans were unsuccessful, and Uniondale remains an unincorporated hamlet governed by the Town of Hempstead.[4]
Musician Frank Zappa's last US performance was at Uniondale in the Nassau Coliseum, in 1988.
According to the United States Census Bureau, the CDP had a total area of 2.7sqmi, all land.[5] [6]
The Uniondale CDP gained territory between the 2010 census and the 2020 census, due to the former CDP of East Garden City being absorbed by the CDP of Uniondale.[7] [8] [9]
Lufthansa United States has its headquarters in Uniondale, moving to the hamlet from adjacent East Meadow in 2019.[10]
At one point, Swiss International Air Lines operated its United States office at 776 RexCorp Plaza in the EAB Plaza in Uniondale. The airline moved its offices from 41 Pinelawn Road in Melville, Suffolk County, around 2002.[11] [12]

The 2014–15 NHL season was originally their final year at the Coliseum before the team moved to the Barclays Center in Brooklyn, New York City. Beginning in 2018, home games were split between Barclays and the Coliseum, and beginning in 2020, the Coliseum once again became the sole home arena for the Islanders until UBS Arena opened in 2021.
