The Kölner Stadt-Anzeiger (KStA) is a German daily newspaper published in Cologne, and has the largest circulation in the Cologne–Bonn Metropolitan Region.

Kölner Stadt-Anzeiger has a base of over 100 contributing editors and a wide network of correspondents for local and regional news reporting.

The Kölner Stadt-Anzeiger first appeared in 1876 as a local equivalent of the national Kölnische Zeitung (Cologne Gazette).

Toward the end of World War II, both newspapers had to cease publication.

Under fierce competition, it developed by the late 1950s into the leading newspaper of the Cologne region.
