DA Donnelly Headshot

Nassau County District Attorney Anne Donnelly has spent her entire professional career following her passion, working as a prosecutor in the Nassau County District Attorney’s Office. Serving the public under three District Attorneys, Donnelly was entrusted with positions of significant responsibility throughout the course of her 32 years as an Assistant District Attorney.  

Elected to the position of Nassau’s top law enforcement officer in 2021, Donnelly's priorities for the office include keeping the residents of Nassau County safe, making sure that dangerous individuals are put behind bars, and providing resources for individuals who need support and assistance. In addition, Donnelly is committed to restoring morale and standing firmly with the staff of the District Attorney’s Office, as well as members of the law enforcement community who work hand-in-hand with prosecutors.

Most recently, Donnelly was the Deputy Bureau Chief of the Organized Crime & Rackets Bureau. In that capacity she was charged with prosecuting long-term investigations into traditional Organized Crime families, as well as large-scale operations engaging in illegal activities, including money laundering. Donnelly was also in charge of overseeing the prosecution of all computer crimes in the office and served as liaison to the Nassau County Correctional Center. 

Prior to her promotion to Deputy Chief in the Organized Crime & Rackets Bureau, Donnelly served as the Deputy Chief of the Economic Crimes Bureau where she was charged with supervising and prosecuting crimes ranging from identity theft to tax fraud, and previously spent more than 12 years prosecuting violent felonies.

Focused on keeping communities safe, Donnelly has been involved in the investigation and successful prosecution of complex murder cases and other prosecutions involving dangerous criminals. Over the course of her career, Donnelly has prosecuted a criminal case involving the sale and distribution of counterfeit electronics, which resulted in the largest asset forfeiture collection in the history of Nassau County; worked with federal prosecutors to successfully convict a physician who filmed and forcibly touched patients; and worked on a Long Beach drug wiretap case, which resulted in the conviction of seven individuals. 

Donnelly is committed to lobbying for substantial changes to New York's broken bail laws, increasing resources in the area of technology and internet crimes, furnishing more assistance for at risk individuals, supporting office staff and law enforcement officers during increasingly difficult times, and providing education and positive alternatives for young people.

Donnelly is a graduate of Fordham University and Fordham Law School. She resides in Garden City with her family.
