Energy absorber may refer to:


 * A panel to absorb the radiant energy of sunlight to heat a fluid, such as solar hot water
 * A bolometer, a device to convert electromagnetic radiation and the momentum of energetic particles to thermal energy which in turn is easily measured
 * A kinetic-energy absorbing medium, sometimes called a crash pit or runaway truck ramp
 * A shock absorber, a device to dampen spring rebound by expending work by forcing a fluid through ports, and so converting the mechanical energy to heat
 * In the context of Fall arrest, an energy absorber is a device that limits the energy of a falling body
 * A material or device to disperse and dissipate impact energy, such as
 * a protective helmet for sports, motorcycling or bicycling
 * armor such as a ballistic vest for protection in warfare
