The Federal Republic of Central America, originally known as the United Provinces of Central America, was a sovereign state in Central America which existed from 1823 to 1839. The federal republic was composed of five states: Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. The federal republic was bordered to the north by Mexico, to the south by Gran Colombia, and on its eastern coastline by the Mosquito Coast and British Honduras.

Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage.
