What is the name of the bar frequented by police officers on the show?

The bar frequented by police officers on The Wire is Kavanagh's Irish Pub.

Kavanagh's is the Baltimore Police Department hangout where detectives and uniformed officers drink, decompress, and gather for traditional wakes honoring fallen colleagues. The bar is especially prominent in season 3, when Detective Ray Cole's body is displayed there and his fellow officers raise glasses and sing Irish songs.

The name is sometimes spelled “Kavanaugh's” in fan guides and filming-location coverage, but “Kavanagh's Irish Pub” is the canonical name commonly used in episode summaries and reference lists. The bar is fictional within the series, even though it was filmed at real Baltimore locations, including the Sidebar Tavern for exterior shots and other venues for interiors.

A common mix-up is confusing the fictional bar with the real Sidebar Tavern, which remains associated with the show’s filming history. Another nearby fact fans often ask about is why the officers hold wakes there: the ritual reflects the close-knit, sometimes rough-edged culture of the Baltimore police department portrayed throughout the series.
