Served from June 1, 1932 to July 1, 1969

Dan Liu was the Honolulu Police Department’s fourth police chief and the longest serving chief. He led the department from 1948 to 1969. He is also the first American police chief of Chinese descent.

As chief, he instituted strong enforcement programs; obtained better salaries, benefits, and working conditions for employees; and improved the training of officers. Many of the changes instituted during his tenure are still in place, such as the redesign of the police badge, change from the original olive drab-colored uniform to navy blue, and the establishment of a chaplaincy corps, a canine corps, and the Police Activities League. He was the first police official from Hawaii to be elected president of the International Association of Chiefs of Police, the largest organization of police executives in the world. Under his leadership, the department gained national prominence.

The Downtown Chinatown Substation was named in his honor in 1990.
