The Siegburg–Olpe railway or Agger Valley Railway (German: Bahnstrecke Siegburg–Olpe or Aggertalbahn) is a single-tracked, non-electrified branch line in the German state of North Rhine-Westphalia. Part of a direct link from Cologne, only the section from Overath to Gummersbach-Dieringhausen is still in operation. The section of line from Siegburg to Overath and from Dieringhausen to Olpe are closed.

The line is named after the River Agger, which it follows for a long way and crosses several times.
