Wiki Collections is a portal page on Archive.org listing all wiki which it has backed up on its site by way of digital preservation. Its main page lists the 'major' wikis which are archived, including the Wikimedia Foundation and the dedicated sub-portal for the WikiTeam.
You can browse a complete list of all wikis it has backed up, and this link shows how many pages it has archived of each wiki (be aware that this page may slow your computer to a crawl – as it lists over 170,000 wiki!).
