The smallest country without a river is Vatican City with a land area of 0.171 sq miles (0.445 sq km). It has no lakes, rivers or mountains and depends on Italy for its water.

The Vatican is an extremely unusual country, in that it is actually a religious city within another country. As it is only a city, it has almost no natural terrain within it, and therefore no natural rivers.

The Vatican is the smallest independent state in the world and residence of the spiritual leadership of the Roman Catholic Church. Its territory is surrounded by the Italian capital city Rome, and priests and nuns of many nationalities make up almost all of the population.
