The Silurian McKenzie Formation (Sm) is a mapped bedrock unit in Maryland.

The McKenzie Formation is a Gray, thin-bedded shale and argillaceous limestone, with interbedded red sandstone and shale in its eastern extents in Maryland. The thickness ranges from 160 to 380 feet.

Relative age dating of the Tuscarora places it in the Silurian period. It rests conformably atop the Clinton Group and conformably below the Bloomsburg Formation.
