he Republic of Cuba (IPA: /ˈkjuːbə/, Spanish: Cuba or República de Cuba (help·info) Spanish pronunciation: [reˈpuβlika ðe ˈkuβa]), consists of the island of Cuba (the largest and second-most populous island of the Greater Antilles), Isla de la Juventud and several adjacent small islands. Cuba is located in the northern Caribbean at the confluence of the Caribbean Sea, the Gulf of Mexico and the Atlantic Ocean. Cuba is south of the eastern United States and The Bahamas, west of the Turks and Caicos Islands and Haiti and east of Mexico. The Cayman Islands and Jamaica are to the south. The national flower is Hedychium coronarium J. Koenig, most often known as "flor de mariposa" (Butterfly Flower) and the national bird is "Tocororo" or Cuban Trogon from the family of Trogonidae. Cuba is the most populous insular nation in the Caribbean. Its people, culture and customs draw from several sources including the aboriginal Taíno and Ciboney peoples, the period of Spanish colonialism, the introduction of African slaves, and its proximity to the United States.
