We introduce inner amenability for discrete p.m.p. groupoids and investigateits basic properties, examples, and the connection with central sequences inthe full group of the groupoid or central sequences in the von Neumann algebraassociated with the groupoid. Among other things, we show that every freeergodic p.m.p. compact action of an inner amenable group gives rise to an inneramenable orbit equivalence relation. We also obtain an analogous result forcompact extensions of equivalence relations which either are stable or have anon-trivial central sequence in their full group.
