Ecuador and Venezuela are separated from Gran Colombia.

Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. It also includes the Galápagos Province which contains the Galápagos Islands in the Pacific, about 1,000 kilometers (621 mi) west of the mainland. The country's capital is Quito and its largest city is Guayaquil.

Venezuela, officially the Bolivarian Republic of Venezuela, is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It comprises an area of 916,445 km² (353,841 sq mi), and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. Venezuela consists of 23 states, the Capital District, and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the north and in the capital.

Gran Colombia, also known as Greater Colombia and officially the Republic of Colombia, was a state that encompassed much of northern South America and parts of Central America from 1819 to 1831. It included present-day Colombia, mainland Ecuador, Panama, and Venezuela, parts of northern Peru, northwestern Brazil, and claimed the Essequibo region. The terms Gran Colombia and Greater Colombia are used historiographically to distinguish it from the current Republic of Colombia, which is also the official name of the former state.
