The name for a narrow strip of land surrounded by water but joined on one end to a larger mass of land is called an isthmus.

Here are some famous examples of isthmuses:

* Isthmus of Panama: Connects North and South America.

* Isthmus of Suez: Connects Africa and Asia.

* Isthmus of Corinth: Connects the Peloponnese peninsula with mainland Greece.
