Ticks are the primary vector of arboviruses in temperate climates worldwide. They are both the vector of these pathogens to humans and an integral component of the viral sylvatic cycle. Understanding the tick‐pathogen interaction provides information about the natural maintenance of these pathogens and informs the development of countermeasures against human infection. In this review, we discuss currently available information on tick‐viral interactions within the broader scope of general tick immunology. While the tick immune response to several pathogens has been studied extensively, minimal work centres on responses to viral infection. This is largely due to the high pathogenicity of tick‐borne viruses; this necessitates high‐containment laboratories or low‐pathogenicity substitute viruses. This has biased most research towards tick‐borne flaviviruses. More work is required to fully understand the role of tick‐virus interaction in sylvatic cycling and transmission of diverse tick‐borne viruses.
