Adds the Piwik Tracking Code to your WordPress blog.
Small but does what you ask him.
While many other plugins comes with too many features from which most I don't use or need, I recommend this plugin because it just works: add Piwik Base URL, and SiteID and you're ready to go.
Works in Network installation too.
