Which Is the Largest Peninsula on Earth?

A peninsula is a piece of land surrounded by water on three of its sides and connected with a larger landmass on its fourth side.

In other words, a land area that “sticks out” into the water. Much of Florida is formed by a peninsula that is surrounded on three sides by the Atlantic Ocean and the Gulf of Mexico.

The largest of all the peninsulas on earth is the Arabian Peninsula in southwest Asia. This landmass is washed on the east by the Persian Gulf, on the west by the Red Sea, and on the south by the Gulf of Aden and the Arabian Sea. The total area of the peninsula is some 1.2 million square miles, more than twice the size of Alaska!

Saudi Arabia is not the only nation on the Arabian Peninsula, although it is by far the largest. In the southern part of the peninsula lie the nations of North Yemen, Southern Yemen, and Oman, and in the east lie Qatar, the United Arab Emirates, and Kuwait.
