Like many such questions about things we don't really understand, the answer is, there could be. 

We know of 3 neutrino species, which actually form a variety of dark matter. These three species are a type of dark matter, but they are not THE dark matter (i.e., they don't have nearly enough mass to explain the observed density of dark matter in the universe). There have been proposals for other, "sterile," neutrino species, which (if the proposals are true)  could supply the needed dark matter. In addition, there are a bunch of proposals for neutrino like particles to supply the dark matter. Of these, the most popular are from  supersymmetry, the neutralino, which probably the most common;y proposed form of dark matter WIMP. 

Of course, there is no real experimental evidence for any of this (except for the 3 known neutrino species) so these particles could be an explanation for dark matter, or they could be just a theoretical dead end. At present, we just don't know.
