Zimbra Collaboration Suite (ZCS) is a groupware product created by Zimbra, Inc., located in Palo Alto, California, USA.

Two versions of Zimbra are available: an open-source version, and a commercially supported version ("Zimbra Network") with closed-source components such as a proprietary MAPI connector to Outlook for calendar synchronization.
