<jats:title>Abstract</jats:title><jats:p>Ecological theory suggests that predators can either keep prey populations healthy by reducing parasite burdens or alternatively, increase parasitism in prey. To quantify the overall magnitude and direction of the effect of predation on parasitism in prey observed in practice, we conducted a meta‐analysis of 47 empirical studies. We also examined how study attributes, including parasite type and life cycle, habitat type, study design, and whether predators were able to directly consume prey contributed to variation in the predator‐prey‐parasite interaction. We found that the overall effect of predation on parasitism differed between parasites and parasitoids and that whether consumptive effects were present, and whether a predator was a non‐host spreader of parasites, were the most important traits predicting the parasite response. Our results suggest that the mechanistic basis of predator‐prey interactions strongly influences the effects of predators on parasites and that these effects, although context dependent, are predictable.</jats:p>
