The Calumet-Saganashkee Channel, usually shortened to the Cal-Sag Channel, is a 16-mile-long (26 km) drainage and shipping canal in southern Cook County, Illinois, operated by the Metropolitan Water Reclamation District of Greater Chicago (MWRD). A component of the Chicago Area Waterway System, it connects the Little Calumet River at its eastern end to the Chicago Sanitary and Ship Canal at its western end.

The Cal-Sag Channel is utilized for inland shipping, recreational boating and drainage purposes in what was an active zone of heavy industry in the Far Southeast Side neighborhoods of the city of Chicago and adjacent suburbs. As a drainage channel, it is used as a conduit for treated effluent wastewater from southern Cook County, including the Chicago-area Deep Tunnel Project, into the Illinois Waterway. It is also used in the summertime by pleasure crafts.
