The Bath School disaster was a series of violent attacks perpetrated by Andrew Kehoe upon the Bath Consolidated School in Bath Township, Michigan, United States, on May 18, 1927. That morning, Kehoe, the school treasurer of Bath Township, detonated explosives he had previously planted underneath the school building, killing 38 people. As rescue efforts began, Kehoe drove to the school in a truck filled with explosives and shrapnel, where he detonated it, killing himself and four others. Earlier the same day, he had also destroyed his farmstead with explosives after having murdered his wife, Nellie Price Kehoe.
