Monk Metcalf is a fictional character on the HBO drama series The Wire, portrayed by Kwame Patterson.

Monk is handed the responsibility of wholesaling drugs to the entire west side of Baltimore by Season Five, when Marlo assumes control of the New Day Co-Op following the murder of Proposition Joe.

He also continues occasional enforcer work when he is involved in a drive-by shooting against a rival crew with Snoop and O-Dog.

Due to the wire tap investigation, Monk is arrested when pulled over and a whole re-up supply of drugs is found in the trunk of his SUV.

However, after Levy's private deal with Rhonda Pearlman, Monk's chances of bail are out of the question, as an earlier charge in 2004 as well as the amount of narcotics found in his SUV effectively gives him a nonnegotiable sentence of up to 20 years in prison.
