List of geographic portmanteaus


This is a list of geographic portmanteaus. Portmanteaus are names constructed by combining elements of two, or occasionally more, other names.
For the most part, the geographic names in this list were derived from two other names or words. Those derived from three or more names are usually considered acronyms or initialisms and can be found in the List of geographic acronyms and initialisms. However, there are exceptions to this two/three rule in both lists, so it is more of a guideline than a hard-and-fast rule.
Note that not all combinations of two names are considered portmanteaus. Simple concatenation of two names does not produce a portmanteau. Nor does a combinative form of one name plus the full name of another. These kinds of names are excluded from this list.

Regions named from their components

Some regions have names that are portmanteaus of subregions or cities within the region.

Countries

Some Chinese provinces have names that are blends of their two largest cities.
During the Joseon Kingdom, seven Korean provinces were named by combining the first characters of their two major cities. The provinces were reorganized in the 1890s but the names are still in use. All these traditional provincial names are carried forward by two current provinces and for all except Gangwon a North and a South province of the same name. However note that for most former provinces, the two current provinces with the name are usually not entirely coextensive with the former province.
The dates of the former provinces are those when they carried that name; they often existed with a different name before that year.
Half of Vanuatu's provincial names are portmanteaus of their main islands or island groups.
Sometimes a portmanteau name is created from the names of predecessor towns. Names that are merely a concatenation of the predecessor names, such as Budapest, are excluded.
Some school districts that serve two or three towns have names that are blends of those towns' names.
A border portmanteau combines the names of two, or occasionally three, adjacent polities to form a name for a region, town, body of water, or other feature on or near their mutual border.

Regions

Generalized border regions

These are generalized regions usually centered on cities near state borders in the United States. They usually extend across state lines and their names are portmanteaus of two or three state names.
§ This symbol marks localities with no current population; some of them never had any population.

Blends of country, state, and province names

Note: places listed on the same line are immediately across the border from each other. Some others with non-similar names are also across a border from each other.
Lakes that are on or near borders also sometimes get named with portmanteaus of the neighbouring polities.
Geographic features on borders or between towns sometimes get border portmanteau names.
These can either run along or near a border or connect two places.

Roads along a border

Below are maps of the towns, bodies of water, and other geographic features that are portmanteaus of country, state, and province names. Also included are pseudo-border portmanteau towns.

Pseudo-border portmanteaus

Some places have names that are blends of country, state, and provincial names. However, they are either not near their mutual border, or of regions that do not have a mutual border.
Most here are blends of two personal names, but some are of a personal name with some other name or word.
