Long Beach Island (colloquially known as LBI) is a barrier island and summer colony along the Atlantic Ocean coast of Ocean County, New Jersey in the United States. Aligned north-south, the northern portion is generally slightly higher end, low-density residential; whereas the southern portion possesses more economical, higher-density housing and considerable commercial development. The primary industries include tourism, fishing, and real estate. The only access point to the island by land is the single bridge, the Causeway, from Manahawkin on the mainland to Ship Bottom on the island. Access is also by water transport. Among the most significant of landmarks on the island is Barnegat Lighthouse, located on the northern tip; the Lucy Evelyn, a ship wreck turned into a shopping venue; and the Holgate Bird Sanctuary on the south end.
Long Beach Island has a humid subtropical climate. In the winter, the island does not get as much snowfall as the northern and western portions of New Jersey or even the immediate inland areas due to its close proximity to the Atlantic Ocean.
