There is no country in the world that doesn't contain a vowel in its name. While some country names might seem to lack vowels, they often contain vowels in their official or common names. For example, "Kyrgyzstan" contains the vowel "y."
While there are many countries with names that have only one vowel, such as "Fiji," "Ghana," and "Qatar," there are no countries that completely lack vowels in their names.
