The Sajdakiem Tunnel (German: Köhlerbergtunnel) is a railway tunnel under Sajdak in the Wałbrzyskie Mountains of south-western Poland, between Jedlina-Zdrój and Głuszyca. It carries the Kłodzko Główne–Wałbrzych Główny railway and forms part of the historic mountain railway infrastructure of the former Prussian Silesia.

The tunnel complex consists of two parallel bores. The first was driven during construction of the Wałbrzych–Kłodzko railway in the late 19th century, and the second was added during the early 20th-century expansion of the line to double track.
