This article lists drivers who have been fatally injured while competing in or in preparation for (testing, practice, qualifying) races sanctioned by the NASCAR. A separate list compiles drivers who have died of a medical condition while driving or shortly thereafter and another section shows non-driver deaths.

There have been 129 deaths of drivers and spectators at NASCAR events. 109 of these deaths were drivers, while 20 were spectators. 14 drivers have also lost their lives at the Daytona International Speedway.^{[citation needed]}

The NASCAR Cup Series has seen 28 driver fatalities, the most recent of which occurred on February 18, 2001, when Dale Earnhardt was killed on the last lap of the Daytona 500.

Safety in the sport has evolved through the decades. Technological advances in roll cages, window nets, seat mounts, air flaps, driving suits, and helmets as well as the HANS device, on-site medical facilities with helicopters, improved track emergency responders, and SAFER barriers have contributed to the prevention of further deaths.

This list covers drivers who crashed their cars because of a fatal medical condition (i.e. drivers who did not die from the injuries they may have sustained in the ensuing accident) as well as those who managed to stop their cars but died of a medical condition shortly afterwards.

This section lists people who have been fatally injured in close connection to the racing taking place at an event while not driving a race car including drivers being on the sidelines.
