==Physical sciences==

===Mathematics and physics===
*[[Displacement (geometry)]], is the difference between the final and initial position of a point trajectory (for instance, the center of mass of a moving object). The actual path covered to reach the final position is irrelevant.
**[[Particle displacement]], a measurement of distance of the movement of a particle in a medium as it transmits a wave (represented in mathematics by the lower-case Greek letter ξ)
**[[Displacement field (mechanics)]], an assignment of displacement vectors for all points in a body that is displaced from one state to another
**[[Electric displacement field]], as appears in Maxwell's equations
*[[Wien's displacement law]], a relation concerning the spectral distribution of blackbody radiation
*[[Angular displacement]], a change in orientation of a rigid body, the amount of rotation about a fixed axis.

===Engineering===
*[[Engine displacement]], the total volume of air/fuel mixture an engine can draw in during one complete engine cycle
*[[Displacement (fluid)]], an object immersed in a fluid pushes the fluid out of the way 
*[[Positive displacement meter]], a pump or flow meter which processes a definite fluid volume per revolution
*Displacement has several meanings related to ships and boats
**[[Displacement hull]], where the moving hull's weight is supported by buoyancy alone and it must displace water from its path rather than planing on the water's surface
**[[Displacement speed]], a rule of thumb for non planing watercraft to estimate their theoretical maximum speed
**[[Displacement (ship)]], the weight of a ship
*[[Insulation displacement connector]], a type of electrical connector
*[[Displacement mapping]], a technique in 3D computer graphics

===Chemistry===
*[[Single displacement reaction]], a chemical reaction concerning the exchange of ions
*[[Double displacement reaction]], a chemical reaction concerning the exchange of ions
*[[Radioactive displacement law of Fajans and Soddy]], elements/isotopes created during radioactive decay

===Geology===
*Earth Crustal Displacement, an aspect of the [[Pole shift hypothesis]]

==Medicine==
*[[Displacement (orthopedic surgery)]], change in alignment of the fracture fragments

==Social sciences==
*[[Displacement (linguistics)]], the ability of humans (and possibly some animals) to communicate ideas that are remote in time and/or space
*[[Forced displacement]], by persecution or violence
*[[Displacement (psychology)]], a sub-conscious defense mechanism
*[[Displacement (parapsychology)]], a statistical or qualitative correspondence between targets and responses.
*[[Development-induced displacement]], the displacement of population for economic development
*[[Gentrification#Displacement|Displacement]] may occur during gentrification.

==Sport==
*[[Displacement (fencing)]], a movement that avoids or dodges an attack

== Economy ==
* [[Layoff]]

==Other==
* [[Child displacement]]
