Gilead or Gilad (Hebrew: גִּלְעָד Gīləʿāḏ, Arabic: جلعاد, Ǧalʻād, Jalaad) is the ancient, historic, biblical name of the mountainous northern part of the region of Transjordan. The region is bounded in the west by the Jordan River, in the north by the deep ravine of the river Yarmouk and the region of Bashan, and in the southwest by what were known during antiquity as the “plains of Moab”, with no definite boundary to the east. In some cases, “Gilead” is used in the Bible to refer to all the region east of the Jordan River. Gilead is situated in modern-day Jordan, corresponding roughly to the Irbid, Ajloun, Jerash and Balqa Governorates.

The Western United States (also called the American West, the Far West, and the West) is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier. The frontier moved westward and eventually the lands west of the Mississippi River were considered the West.

The Outback is a vast, sparsely populated area of Australia. The Outback is more remote than the bush, which includes any location outside the main urban areas.

The Celtic nations is a cultural region and collection of geographical territories in Western Europe and the North Atlantic where Celtic languages and/or cultural traits have survived. The term "nation" is used in its original sense to mean a people who share a common identity and culture and are identified with a traditional territory.

The Great Rift Valley is a series of contiguous geographic trenches, approximately 6,000 kilometres (3,700 mi) in total length, that runs from the Beqaa Valley in Lebanon in Asia to Mozambique in southeastern Africa. While the name continues in some usages, it is rarely used in geology as it is considered an imprecise merging of separate though related rift and fault systems.

MENA, also known as MENAP, is an English-language acronym referring to the Middle East, North Africa, Afghanistan, and Pakistan, which corresponds to the Greater Middle East. Another name for the region (excluding Afghanistan and Pakistan) is WANA (Western Asia and North Africa). MENA covers an extensive region stretching from the Maghreb in the west to Pakistan in the east. The MENA acronym is often used in academia, military planning, disaster relief, media planning as a broadcast region, and business writing.

The Chad Basin is the largest endorheic basin in Africa, centered on Lake Chad. It has no outlet to the sea and contains large areas of desert or semi-arid savanna. The drainage basin is roughly coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans eight countries, including most of Chad and a large part of Niger. The region has an ethnically diverse population of about 30 million people as of 2011, growing rapidly.

Tumbes-Chocó-Magdalena is a biodiversity hotspot, which includes the tropical moist forests and tropical dry forests of the Pacific coast of South America and the Galapagos Islands. The region extends from easternmost Panama to the lower Magdalena Valley of Colombia, and along the Pacific coast of Colombia and Ecuador to the northwestern corner of Peru. Formerly called the Chocó-Darién-Western Ecuador Hotspot, it has been expanded to include several new areas, notably the Magdalena Valley in northern Colombia. It is bounded on the east by the Andes Mountains. The Tumbes-Choco-Magdalena Hotspot is 1,500 km long and encircles 274,597 km². Tumbes-Choco-Magdalena is near the Pacific Ocean. The factors that threaten Tumbes-Choco-Magdalena are farming encroachment, deforestation, illegal crops, and population growth. Whereas the Panamanian and Colombian portion of the hotspot are relatively intact, approximately 98% of native forest in coastal Ecuador has been cleared, rendering it the most threatened tropical forest in the world. The hotspot includes a wide variety of habitats, ranging from mangroves, beaches, rocky shorelines, and coastal wilderness to some of the world's wettest rain forests in the Colombian Chocó. The hotspot includes a number of ecoregions:

Northeast Asia, North East Asia or Northeastern Asia is a term to refer to a subregion of Asia: the northeastern landmass and islands, bordering the Pacific Ocean. It includes the core countries of East Asia.
