  We consider the possibility that a massive fourth family neutrino, predicted
by a recently proposed minimal technicolor theory, could be the source of the
dark matter in the universe. The model has two techniflavors in the adjoint
representation of an SU(2) techicolor gauge group and its consistency requires
the existence of a fourth family of leptons. By a suitable hypercharge
assignement the techniquarks together with the new leptons look like a
conventional fourth standard model family. We show that the new (Majorana)
neutrino N can be the dark matter particle if $m_N \sim 100-500$ GeV and the
expansion rate of the Universe at early times is dominated by an energy
component scaling as $\rho_\phi \sim a^{-6}$ (kination), with
$\rho_\phi/\rho_{\rm rad} \sim 10^{-6}$ during the nucleosynthesis era.
