Map of Tonga

Tonga is located in Oceania. Its territory lies in the southern and western hemispheres, centred near 20.0° S, 175.0° W. It is an island nation and shares no land borders with any other country, so every approach to it is made by sea or by air. Within Oceania, a continent of 14 countries bordered by the Pacific Ocean, the Indian Ocean and the Southern Ocean, Tonga is mapped here in full with its borders, capital and key facts.

Tonga is an island state with no land borders. The nearest countries are reached across open water rather than over a shared frontier.

Tonga keeps a single standard time zone, UTC+13:00. That figure is the country’s offset from Coordinated Universal Time (UTC), the modern reference that for everyday purposes matches Greenwich Mean Time, so local clocks sit +13:00 relative to UTC before any seasonal daylight saving change.

The official currency is the Tongan paʻanga (TOP, T$).

The official languages are English and Tongan, which is what appears on signs, documents and many of the place labels you will see on the map.
