Trinidad and Tobago (ⁱ/ˌtrɪnɨdæd/ & /tɵˈbeɪɡoʊ/) officially the Republic of Trinidad and Tobago is an archipelagic state in the southern Caribbean, lying just off the coast of northeastern Venezuela and south of Grenada in the Lesser Antilles. It shares maritime boundaries with other nations including Barbados to the northeast, Guyana to the southeast, and Venezuela to the south and west.

The country covers an area 5,128 square kilometres (1,980 sq mi) and consists of two main islands, Trinidad and Tobago, and numerous smaller landforms. Trinidad is the larger and more populous of the main islands, comprising about 94% of the total area and 96% of the total population of the country. The nation lies outside the hurricane belt.

The island of Trinidad was a Spanish colony from the arrival of Christopher Columbus in 1498 to the capitulation of the Spanish Governor, Don José Maria Chacón, on the arrival of a British fleet of 18 warships on 18 February 1797. During the same period, the island of Tobago changed hands between Spanish, British, French, Dutch and Courlander colonizers. Trinidad and Tobago was ceded to Britain in 1802 under the Treaty of Amiens. The country obtained independence in 1962, becoming a republic in 1976. Unlike most of the English-speaking Caribbean, Trinidad and Tobago's economy is primarily industrial, with an emphasis on petroleum and petrochemicals.

Tobago ( /təˈbeɪɡoʊ/) is the smaller of the two main islands that make up the Republic of Trinidad and Tobago. It is located in the southern Caribbean, northeast of the island of Trinidad and southeast of Grenada. The island lies outside the hurricane belt. According to the earliest English-language source cited in the Oxford English Dictionary, Tobago bore a name that has become the English word tobacco.

Tobago has a land area of 300 km² (116 mi²), and is approximately 42 km (26 mi) long and 10 km (6.2 mi) wide. It is located at latitude 11° 9' N, longitude 60° 40' W, slightly north of Trinidad. The population is 54,084 (2000). The capital is Scarborough which has a population of about 17,000. While Trinidad is multiethnic, the population of Tobago is primarily of African descent, although with a growing proportion of Trinidadians of East Indian descent and Europeans (predominantly Germans and Scandinavians). Between 1990 and 2000, the population of Tobago grew by 11.28 percent, making it one of the fastest growing areas of the country.
