**Quantum theory provides a framework for modern theoretical physics that enjoys enormous predictive and explanatory success. Yet, in view of the so-called “measurement problem”, there is no consensus on how physical reality can possibly be such that this framework has this success. The theory is thus an extremely well-functioning algorithm to predict and explain the results of observations, but no consensus on which kind of objective reality might plausibly underlie these observations.**

**Amongst the many attempts to provide an “interpretation” of quantum theory to account for this predictive and explanatory success, one class of interpretations hypothesizes backward-in-time causal influences—retrocausality—as the basis for constructing a convincing foundational account of quantum theory. This entry presents an overview of retrocausal approaches to the interpretation of ****quantum**** theory, the main motivations for adopting this approach, a selection of concrete suggested retrocausal models, and a review of the objections brought forward against such approaches.**
