Law enforcement agencies in Maine provide public safety, criminal investigation, wildlife enforcement, and corrections across Maine through a network of Maine State Police, county sheriffs, municipal police departments, tribal police, campus public safety, and federal agencies. The system interacts with institutions such as the Maine Department of Public Safety, the Maine Department of Inland Fisheries and Wildlife, the Maine Department of Corrections, and federal entities including the Federal Bureau of Investigation, Drug Enforcement Administration, and United States Marshal Service. Coordination frequently involves multijurisdictional task forces, mutual aid agreements, and statewide initiatives tied to statutes in the Maine Revised Statutes and programs administered from the Maine State Police Training Academy.

State agencies

The primary state-level enforcement body is the Maine State Police, which works with the Maine Department of Public Safety, the Maine Department of Inland Fisheries and Wildlife (game wardens), and the Maine Department of Transportation's motor carrier enforcement to regulate highways, fisheries, and commercial vehicles. The Maine Department of Corrections oversees adult correctional facilities and probation services, while the Maine Warden Service enforces natural resource laws alongside the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration. Specialized statewide units include the Maine Drug Enforcement Agency task forces partnering with the Drug Enforcement Administration and the Federal Bureau of Investigation for narcotics, cybercrime, and counterterrorism investigations.

County agencies

Each of Maine's counties maintains an elected County sheriff and a sheriff's office—examples include the Cumberland County Sheriff's Office, York County Sheriff's Office, Penobscot County Sheriff's Office, and Kennebec County Sheriff's Office—responsible for court security, jail operations, civil process, and countywide law enforcement operations. County agencies routinely coordinate with the Maine State Police, municipal police departments, and federal partners such as the United States Marshal Service, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the Internal Revenue Service Criminal Investigation. Regional initiatives often involve county-level task forces, emergency management through Maine Emergency Management Agency, and inter-county mutual aid under guidelines in the Maine Emergency Response System.

Municipal police departments

Municipal policing in Maine ranges from small-town departments like the Stonington Police Department and Bar Harbor Police Department to larger agencies such as the Portland Police Department and the Lewiston Police Department, providing patrol, investigations, traffic enforcement, and community policing. Departments collaborate with entities including the Harbor Master offices, Maine Turnpike Authority Police functions tied historically to the Maine Turnpike Authority, and regional narcotics task forces supported by the Drug Enforcement Administration and Federal Bureau of Investigation. Municipal officers receive training at the Maine Criminal Justice Academy and may work with the Coast Guard in maritime operations or with county sheriffs on jail transports and civil process.

Tribal law enforcement

Tribal public safety is provided by federally or tribally recognized police forces such as the Penobscot Nation Tribal Police and the Passamaquoddy Tribal Police, which enforce tribal ordinances and work with the Bureau of Indian Affairs and the Federal Bureau of Investigation on major crimes. Tribal agencies coordinate with the Maine Warden Service, county sheriffs, and the Maine Department of Public Safety on cross-jurisdictional issues, natural resources enforcement near reservation lands, and joint public safety initiatives tied to sovereign authority and treaties like those involving the Penobscot Nation and Passamaquoddy Tribe.

College and university police

Campus safety is handled by entities such as the University of Maine Police Department at Orono, the University of Southern Maine Police Department, and campus public safety units at institutions like Bowdoin College and Colby College, which provide policing, crime prevention, and liaison with local, county, and state law enforcement. These agencies often collaborate with the Maine State Police, FBI Safe Streets Task Force partners, and campus emergency management connected to the Maine Emergency Management Agency and federal campus safety programs arising from federal statutes and Department of Education guidance.

Specialized and federal agencies operating in Maine

Federal law enforcement operating in Maine includes the Federal Bureau of Investigation, Drug Enforcement Administration, Bureau of Alcohol, Tobacco, Firearms and Explosives, United States Marshal Service, U.S. Immigration and Customs Enforcement, and the United States Coast Guard, which perform investigations, maritime security, and counterterrorism. Specialized state or bi-state entities include the Maine Turnpike Authority Police functions, the Maine State Police Tactical Team, wildlife enforcement by the Maine Department of Inland Fisheries and Wildlife, and forensic services at the Maine State Police Crime Lab, often supporting federal prosecutions in collaboration with the United States Attorney for the District of Maine.
