This article describes the geography of Grenada.

Grenada is a Caribbean island (one of the Grenadines) between the Caribbean Sea and Atlantic Ocean, north of Trinidad and Tobago. It is located at . There are no large inland bodies of water on the island, which consists entirely of the state of Grenada. The coastline is 121 km long.

The island has 15 constituencies and speaks English. It is volcanic in origin and its topography/landscape is mountainous.

Natural resources include timber, tropical fruit and deepwater harbors.

Grenada and its largely uninhabited outlying territories are the most southerly of the Windward Islands. The Grenadine Islands chain consists of some 600 islets; those south of the Mount St. Catherine is the highest peak at 840 meters.

Although many of the rocks and soils are of volcanic origin, the volcanic cones dotting Grenada are long dormant. The only known active volcano in the area is Kick 'em Jenny, just north between Grenada and Carriacou. Some of the drainage features on Grenada remain from its volcanic past. There are a few crater lakes, the largest of which is Grand Etang. The swift upper reaches of rivers, which occasionally overflow and cause flooding and landslides, generally cut deeply into the conic slopes. By contrast, many of the water courses in the lowlands tend to be sluggish and meandering.

The Grenadan climate is tropical, tempered by northeast trade winds. The land is volcanic in origin with mountains in the interior. The lowest point is at sea level, and the highest is 840 m (2,756 ft) on Mount Saint Catherine.

The abundance of water is primarily caused by the tropical, wet climate. Yearly precipitation, largely generated by the warm and moisture-laden northeasterly trade winds, varies from more than 3,500 millimeters (137.8 in) on the windward mountainsides to less than 1,500 millimeters (59.1 in) in the lowlands. The greatest monthly totals are recorded throughout Grenada from June through November, the months when tropical storms and hurricanes are most likely to occur. Rainfall is less pronounced from December through May, when the equatorial low-pressure system moves south. Similarly, the highest humidities, usually close to 80 percent, are recorded during the rainy months, and values from 68 to 78 percent are registered during the drier period. Temperatures averaging 29 °C (84.2 °F) are constant throughout the year, however, with slightly higher readings in the lowlands. Nevertheless, diurnal ranges within a 24-hour period are appreciable: between 26 and 32 °C (78.8 and 89.6 °F) during the day and between 19 and 24 °C (66.2 and 75.2 °F) at night.
