Most Dangerous Cities in Maine

FBI UCR Highest-Crime Snapshot: Maine

Maine's 21 highest-crime cities for 2024 range from Biddeford at the top with a violent crime rate of 313.8/100K down to Gorham at 21.8/100K — all sitting above most US municipal averages. The list draws on FBI Uniform Crime Reporting (UCR) Program Table 8 submissions and restricts inclusion to cities of 10,000 residents or more so that per-capita rates reflect enough underlying offenses to be statistically meaningful. Across these 21 Maine cities the average violent crime rate reaches 127.2 per 100,000 residents, a figure that typically exceeds the US national violent crime benchmark by a wide margin.

At the top of the ranking, Biddeford recorded 70 violent crimes and 524 property crimes against a reporting population of 22,310 in 2024. That produces a property crime rate of 2348.7 per 100,000 residents alongside the 313.8/100K violent rate, with both Part I crime categories elevated compared to state and national benchmarks. The five most dangerous Maine cities on this list are Biddeford, Portland, Augusta, Lewiston, Auburn, each submitting Part I offense counts to the FBI UCR Program for 2024.

Elevated per-capita rates can reflect multiple factors beyond raw crime volume: small reporting populations amplify year-to-year rate volatility, transient or tourist populations dilute resident denominators, and municipal boundaries sometimes exclude higher-income suburbs that would otherwise balance the total. UCR figures also reflect offenses reported to and submitted by local law enforcement and can miss unreported crime entirely, so rankings measure visible, recorded crime rather than absolute community conditions. Readers comparing these cities with others across Maine can use the A-F safety grades page or national rankings to contextualize how 2024 figures stack up against peers nationwide.
