Cologne I (German: Köln I) is one of the four electoral districts (German: Wahlkreis) covering the city of Cologne in the German Bundestag. Part of the state of North Rhine-Westphalia, the constituency elects one representative under the mixed member proportional representation (MMP) system. Under the current constituency numbering system, it is designated as constituency 94.
Covering the south eastern quarter of the city of Cologne, the constituency contains the entirety of two of the city's nine districts: Porz and Kalk. It also stretches into the city centre to include three of the five areas of the Innenstadt district: Altstadt-Nord, Deutz and Neustadt-Nord. The latter area includes about half of Cologne's old and new town areas.
