Siehdichum is a municipality in the Oder-Spree district, in Brandenburg, Germany. The name literally means "have a look around you".
The municipality of Siehdichum was formed in 2003 by merging the municipalities of Pohlitz, Rießen and Schernsdorf.
From 1815 to 1947, the constituent localities of Siehdichum were part of the Prussian Province of Brandenburg.
After World War II, Pohlitz, Rießen and Schernsdorf were incorporated into the State of Brandenburg from 1947 to 1952 and the Bezirk Frankfurt of East Germany from 1952 to 1990. Since 1990, they are again part of Brandenburg, since 2003 united as the municipality of Siehdichum.
