Abstract
We prove that every (not necessarily linear nor continuous) 2-local triple derivation on a von Neumann algebra $M$ is a triple derivation, equivalently, the set $\operatorname{Der}_{t}(M)$, of all triple derivations on $M$, is algebraically 2-reflexive in the set $\mathcal{M}(M)=M^{M}$ of all mappings from $M$ into $M$.
