In helicopters the rotorhead is the part of the rotor assembly that joins the blades to the shaft, cyclic and collective mechanisms. It is sometimes referred to as the rotor "hub". Rotorhead is also slang for helicopter pilots, engineers and enthusiasts of rotary-wing aircraft, similar to "propellerhead" for fixed-wing aircraft.

"Rotorhead" may also refer to an enthusiast of Wankel rotary engines, especially Mazda RX-7s and RX-8s.
