Maui County Police Department, Law enforcement headquarters in Wailuku, Hawaii.

The Maui County Police Department is the law enforcement agency serving Maui, Molokai, and Lanai islands with multiple district stations throughout the area. It handles all policing and public safety matters across the three-island jurisdiction.

The County Act of 1905 split Maui County into five districts, each electing a deputy sheriff, and William Saffrey became Sheriff of Maui County. In 1939 the Governor appointed a Police Commission and created the Maui County Police Department, with George Fritchoff Larsen, Jr. as first Chief of Police. In 1940 the department had 76 employees and spent $134,474.

The department's badge changed in 1970 from a star-in-circle to an eagle design, and patrol uniforms went from dark green to light blue shirts with dark blue trousers, then to all dark blue in 1980. The county's parade banner is divided light blue, light green and light blue by red stripes, with a seal at the centre.

The department serves a jurisdiction of 2,398 square miles, of which 1,162 square miles is land spread across Maui, Lānaʻi, Molokaʻi, Kahoʻolawe and Molokini. The county seat and department base is Wailuku; the uninhabited islands of Kahoʻolawe and Molokini also fall within county limits. The current chief is John Pelletier.
