Cold fusion is a hypothesized type of nuclear reaction that would occur at or near room temperature.

Cold fusion may also refer to:

In science Muon-catalyzed fusion, before Fleischmann and Pons, was sometimes called cold fusion Pyroelectric fusion, first achieved in 2005, uses a pyroelectric crystal to accelerate ions to fusion energies with room temperature equipment Polywell fusion, uses inertial electrostatic confinement to attract and confine ions so densely that they fuse Nuclear fusion where the product nuclei have a relatively low excitation energy of around 10 to 20 MeV (this meaning is used mostly in the field of the synthesis of superheavy elements)
