A Purple Alert is an emergency alert system used in Florida to assist in the location of missing adults who have a mental or cognitive disability that is not Alzheimers disease or a dementia-related disorder, an intellectual disability or a developmental disability, a brain injury, other physical, mental, or emotional disabilities that are not related to substance abuse, or a combination of any of these and whose disappearance poses a credible threat of immediate danger or serious bodily harm. The Purple Alert Plan was added to the Florida Department of Law Enforcements emergency alert system in 2022.

If an agency determines that a case meets the criteria for a Purple Alert, they will contact the FDLE Missing Endangered Persons Information Clearinghouse. The alert notifies the public using email or text alerts throughout the state, with a focus on the area where the person was last seen. The Purple Alert engages the public in the search for the missing person and provides a standardized and coordinated community response.

In summary, a Purple Alert is a type of emergency alert system used in Florida to locate missing adults with a mental or cognitive disability that is not Alzheimers disease or a dementia-related disorder, an intellectual disability or a developmental disability, a brain injury, other physical, mental, or emotional disabilities that are not related to substance abuse, or a combination of any of these and whose disappearance poses a credible threat of immediate danger or serious bodily harm.
