The Calendar and Contacts Server project is an Apple-developed standards-compliant server implementing the CalDAV and CardDAV protocols. It provides a shared location on the network allowing multiple users to store and edit calendaring and contact information. The server was publicly released during Apple's Worldwide Developers Conference on August 7, 2006 as iCal Server and Address Book Server.

The server, named "caldavd", is a daemon background service. It has been ported to non-Apple computer platforms. It is currently possible to install it on FreeBSD and several flavours of Linux. The server is written in the Python programming language with the Twisted framework, and uses an SQL database for storage of calendar data.

Server 5.7.1, the version aligned with macOS 10.14 and released on September 30, 2018, removed the Calendar and Contacts Server functionality from Server.app.
