Emergency Digital Information Service (EDIS) is a wireless datacast based emergency and disaster information service operated by the State of California Governor's Office of Emergency Services.

The system is an enhancement to the Emergency Alert System.{{cite book |last1=Petersen |first1=J.K. |title=Fiber Optics Illustrated Dictionary |date=2018 |publisher=CRC Press |isbn=9781351836166 |url=https://books.google.com/books?id=DgJ-DwAAQBAJ |access-date=20 June 2023}} Like the EAS, it is used for statewide and local emergencies such as severe weather warnings, AMBER Alerts,{{cite book |title=An AMBER Alert national system |date=2003 |publisher=U.S. Government Printing Office |isbn=9780160704529 |page=33 |url=https://books.google.com/books?id=x2W39xGtqZIC&dq=%22Emergency+Digital+Information+Service%22&pg=PA33 |access-date=20 June 2023}} and civil emergencies.
