Never Again MSD is an American student-led political action committee for gun control that advocates for tighter regulations to prevent gun violence. The organization, also known by the Twitter hashtags #NeverAgain, and #EnoughIsEnough, was formed by a group of twenty students attending the Marjory Stoneman Douglas High School (MSD) at the time of the deadly shooting in 2018, in which seventeen students and staff members were killed by the alleged gunman, who was a former student at the school and armed with an AR-15 style semi-automatic rifle. The organization started on social media as a movement "for survivors of the Stoneman Douglas Shooting, by survivors of the Stoneman Douglas Shooting" using the hashtag #NeverAgain. A main goal of the group was to influence the 2018 United States elections, and they embarked on a multi-city bus tour in June 2018 to encourage young people to register to vote.
