{{Short description|Space available for deposition of sediments}}
'''Accommodation''' in geology is the space that is available for the deposition of sediments.<ref name="patzkowskyholland30" > {{cite book |last1=Patzkowsky |first1= Mark E. |first2=Steven M. |last2=Holland|year= 2012|title=Stratigraphic Paleobiology |location=Chicago |publisher=University of Chicago University Press|pages=30}} </ref><ref name="catuneanu"> {{Cite journal|last=Catuneanu|first=Octavian|date=2011|title=Sequence stratigraphy: methodology and nomenclature|language=en|publisher=E.

In marine environments, this equilibrium level is sea level.<ref>{{cite book |last1=Boggs |first1=Sam |title=Principles of sedimentology and stratigraphy |date=2006 |publisher=Pearson Prentice Hall |location=Upper Saddle River, N.J. |isbn=0131547283 |page=451 |edition=4th}}</ref>
In marine environments, changes in accommodation on long temporal scales are mainly determined by tectonics or by changes in eustatic sea level. In fluvial environments, changes in accommodation are controlled by the gradient, discharge and sediment supply. In the lower parts of river systems, the change of accommodation in the fluvial system is controlled by the changes in marine accommodation.<ref name="catuneanu"/>
The term is also sometimes used to describe processes by which room is made for plutons to intrude country rock.<ref name="fernandez-castro-1999">{{cite journal |last1=Fernández |first1=Carlos |last2=Castro |first2=Antonio |title=Pluton accommodation at high strain rates in the upper continental crust.
