For a list of Wikimedia events, see the Events page on Meta.

The following are the meetings, conferences and hacking sessions related to MediaWiki and Wikimedia code development that have either been held already, or are scheduled for the future. This page lists events that are primarily focused on MediaWiki- and Wikimedia-related development; this does not include events where software may be discussed, but it's not a main focus, like Wikimania (the main conference part).
