Alofi is the capital of the island nation of Niue. With a population of 610 in 2022,^[4] Alofi has the distinction of being the second-smallest capital city of a sovereign state by population (after Ngerulmud, capital of Palau). It consists of two villages: Alofi North and Alofi South. They collectively serve as the capital, but of the two, Alofi South hosts more government buildings, as many were moved to the southern part after Cyclone Heta.

In January 2004, Niue was hit by the fierce tropical storm Cyclone Heta, which killed two people and did extensive damage to the entire island. Many of Alofi's buildings were destroyed, including the hospital. Government buildings were shifted to a less exposed site 3 km (≈ 2 mi) inland from the west coast,^[6] named Fonuakula, after the storm.^[7] This site is within the village boundaries of Alofi South.

The town is serviced by Niue International Airport, and there are numerous roads, both paved and dirt, that crisscross the town.^[10]

The island's main seaport is Sir Roberts Wharf. It is located at 19°03′10″S 169°55′15″W, close to the centre of Alofi, within 200 metres of the capital's post office and just to the north of the Chamber of Commerce building. It is a small wharf, capable – due to the island's topography — of only handling smaller flat-bottomed boats. Larger cargo vessels and fishing boats moor near the reef, and barges are used to offload cargo. Major strengthening, extension work, and renovations to the wharf were commissioned in 2020, after cyclone damage earlier in the year.^[11]
