The names of the men, women, and children killed as a result of the 9/11 attacks have been read aloud at the official 9/11 anniversary commemoration in New York City every year. This list of names inscribed on the 9/11 Memorial includes all those killed in the 9/11 attacks and the six individuals killed in the 1993 World Trade Center bombing.

The 9/11 Memorial Guide allows users to select specific victim names or groups of names, including names of individuals from a certain town or state, a specific company, or first-responder agency.

Lower flags to half-staff on the anniversary of 9/11. Flags may be lowered at 8:46 a.m. to mark the moment when Flight 11 struck the North Tower.

Twenty years later, Americans remember the events of 9/11 and reflect on the stories of hope and resilience, sacrifice and service, goodwill and community that inspired us all in the aftermath of 9/11 and do so again today. By hosting a fundraising event in your community, you can commemorate the 20th anniversary of 9/11 and support The Never Forget Fund. The 9/11 Memorial & Museum will send video and other digital assets to you to display at your event. To learn more and receive your hosts’ digital toolkit, email jvonnatterer@911memorial.org
