Every massive globular cluster (GC) is expected to harbour a significant
population of cataclysmic variables (CVs). In this review, I first explain why
GC CVs matter astrophysically, how many and what types are theoretically
predicted to exist and what observational tools we can use to discover, confirm
and study them. I then take a look at how theoretical predictions and observed
samples actually stack up to date. In the process, I also reconsider the
evidence for two widely held ideas about CVs in GCs: (i) that there must be
many fewer dwarf novae than expected; (ii) that the incidence of magnetic CVs
is much higher in GCs than in the Galactic field.
