Dark Forces Searches at KLOE-2

Direct searches of dark matter are performed at accelerator facilities. The existence of a new vector boson has been postulated in different scenarios where in the most basic scheme the coupling to the SM can be achieved via a kinetic mixing term due to the U boson. The KLOE experiment at DA$\phi$NE searched for the U boson both in Dalitz decays of the $\phi$ meson and in continuum events. For all of these searches an upper limit for the U boson coupling $\epsilon^{2}$ has been established in the mass range $50 \, \text{MeV} < m_U < 1000\,\text{MeV}$. A summary of the different models and searches along with results are presented.
