Landlocked countries are those which are geographically surrounded by land and do not touch an ocean, sea, or other body of water. Roughly one-fifth of the world's countries are landlocked (such as Uganda, Ethiopia, and Austria), as are 21 US states. There are also two double-landlocked countries, which are not only landlocked, but also completely surrounded by countries which are also landlocked. A triple-landlocked country would be one ringed by double-landlocked countries-however, no triple-landlocked countries exist.
