Extraterrestrial neutrinos can be used to probe the presence of dark matter in the Milky Way. Pair annihilation and decay of dark matter particles could give rise to sizable fluxes of high-energy neutrinos detectable with large volume Cherenkov telescopes. The Galactic Centre is one of the most promising sources for these searches. Telescopes installed in the Mediterranean Sea are best suited to look for dark matter from this source. Another interesting source to study is the Sun, given its proximity. Moreover, it is a source almost free of astrophysical background. The ANTARES neutrino telescope has been taking data in the Mediterranean, offshore the French coast, for 16 years and has been decommissioned in 2022. The detector had a very good resolution in determining the direction and energy of the incoming neutrinos.
The expected space and energy distributions of dark matter overdensity regions are used to characterise the searched signal over a (known) diffuse background of atmospheric neutrinos. In this contribution we present the most relevant results of dark matter searches with the full ANTARES data sample. A search for signatures of Weakly Interacting Massive Particles (WIMPs) has been performed with electron- and muon-neutrino data, in an energy range from 50 GeV/c$^2$ to 100 TeV/c$^2$.
All these searches set competitive upper limits on the strength of dark matter pair annihilation which are reported here.
