This is a list of geographic portmanteaus. Portmanteaus (also called blends) 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.
