The existence of dark matter (DM) has been well-established by repeated experiments probing various length scales. Even though DM is expected to make up 85% of the current matter content of the Universe, its nature remains unknown. Numerous methods have been developed to search for DM—both directly by looking for excess energy created in DM interaction with normal matter and indirectly by looking or DM's effect on normal matter. The IceCube Neutrino Observatory—a cubic-kilometer of instrumented ice located beneath the geographic South Pole, which detects Cherenkov radiation of charged particles produced in neutrino interactions—is well-suited to the latter class of searches. Depending on the nature of DM, IceCube may observe, among other signatures, an excess of neutrinos, a modified directional distribution, or a modified flavor distribution. In this contribution, I will highlight IceCube's recent indirect DM searches and their results.
