Brother Mouzone is a fictional character on the HBO drama The Wire, played by actor Michael Potts.

Brother Mouzone (from Arabic موزون mawzūn, meaning "balanced,” "weighted") is a drug enforcer and hitman from New York City.

"The Brother" does not fit the usual picture of drug-trade "muscle"; he always wears a suit, bowtie, and glasses, and speaks politely and precisely.

Upon first encountering him, the street dealer Cheese mocked Mouzone's formal style of dress by remarking that he must either be in "the Nation" or still let his mother pick out his clothes.

Rather than exact vengeance on Omar for shooting him, Mouzone suggests that they find and kill Stringer Bell together.
