Probing dark matter with ILC

The International Linear Collider (ILC) offers a number of unique opportunities for searching dark sector particles in e+e− collisions. The collider program itself will offer important capabilities, including precision measurements in the Higgs sector and direct searches based on the monophoton signature. With extreme intensities of the high-energy electron and positron beams, the ILC will also enable new fixed-target measurements, both beam dump experiments and dedicated experiments using extracted beams. Described in this contribution are the expectations for these programs, which address various possible dark sector portals.
