Interwikis (short for interwikimedia links) are links between wikis. These often show links to the same page in other languages. They can also be used to link to other projects, such as Wiktionary and Wikimedia Commons.

It is important to have interwikis to other languages. They help people to find more information and other Wikipedias. Most articles on the Simple English Wikipedia have pages in the English Wikipedia or other languages.
