Rescue 911 is an informational docudrama television series that premiered on CBS on April 18, 1989, and ended on August 27, 1996. The series was hosted by William Shatner and featured reenactments (and occasionally real footage) of emergencies that often involved calls to 911.

Though never intended as a teaching tool, various viewers used the knowledge they obtained watching the show. Two specials, titled 100 Lives Saved and 200 Lives Saved, were dedicated to these viewers who had written to CBS with their stories on how the knowledge they obtained watching the show allowed them to save the life of someone else. At least 350 lives have been saved as a result of what viewers learned from watching it. The show's popularity coincided with, if not led, to the widespread adoption of the 911 emergency system, replacing standalone police and fire numbers that would vary from municipality to municipality. The number is now universally understood in the United States and Canada to be the number dialed for emergency assistance.

At its height, the show was adapted in 45 countries (with their own 911 equivalent showcased).
