Despite the effort, dark matter searches have so far come up empty handed. Indirect searches of dark matter using neutrino yields also have had no luck, but they have served important role as a complementary tool to the direct searches. Until now, searches have focused on dark matter with masses ranging from a few GeV to a few TeV, due to direct detection setups losing their sensitivities to masses below a few GeV, also because of WIMP paradigm. The null result, despite not completely ruled out, suggests a possibility that dark matter may not be connected to the electroweak scale, and search strategies need to expand beyond the WIMP paradigm. Large-volume neutrino detectors, with their high collecting efficiencies to rare signals, will naturally take a leading role in future dark matter searches. In this talk, I will review recent dark matter searches with IceCube, Super-Kamiokande and other neutrino experiments, and introduce some future plans.
