Police Chief Clancy Wiggum (voiced by Hank Azaria) is a fictional character from the animated television series The Simpsons.

Clancy Wiggum was possibly born in Baltimore, Maryland. He mentioned he used to sell ribbons there with his father, Iggy. Iggy was a war veteran who died in a parade float accident in 1979, along with Arnie Gumble, Sheldon Skinner, Etch Westgrin, and Griff McDonald, all members of Abe Simpson's Flying Hellfish. Apparently he did however grow up in Springfield and was among the same class and age group as Homer Simpson, Lenny Leonard, Carl Carlson, Barney Gumble, and possibly Marge Simpson.

Wiggum is the chief of police of the Springfield police department. He is an extreme stereotype: morbidly obese, dim witted, ignorant, grossly incompetent, lazy, with a fondness for doughnuts and "Chintzy Pop". His voice is based on Edward G. Robinson's. He has little regard for individual rights or even public safety. He is disturbingly uninformed ("Some Chinese people claimed they were celebrating New Year's in February ... good food though") and flaunts his power, albeit with good intentions most of the time. He, along with the rest of Springfield's government and police force, is also corrupt, having asked for or taken bribes several times. As an example of this, in The Simpsons Spin-Off Showcase he moves to New Orleans after being kicked off the Springfield Police Force for massive corruption, although this segment was something of a spoof. He has also notably solicited Troy McClure and Homer Simpson for bribes in exchange for "looking the other way" to their criminal activities. He has a strained relationship with Mayor Quimby, as the two men vie to have control over the city (once leading to a serious argument over who takes over during an emergency during the Monorail crisis). Wiggum claims to have compromising photographs of the mayor ("You don't scare me; that could be anyone's ass!"), which may help to explain why he has retained his job despite a general lack of competence.
