  Dark matter remains one of the most puzzling mysteries in Fundamental Physics
of our times. Experiments at high-energy physics colliders are expected to shed
light to its nature and determine its properties. This review talk focuses on
recent searches for dark-matter signatures at the Large Hadron Collider, either
within specific theoretical scenarios, such as supersymmetry, or in a
model-independent scheme looking for mono-X events arising in WIMP-pair
production.
