There are 57 recorded species of Odonata in Britain, made up of 21 damselflies (suborder Zygoptera) and 36 dragonflies (suborder Anisoptera). Of these, 42 species (17 damselflies and 25 dragonflies) are resident breeders, and the remainder are either extinct species, or vagrants - in respect of the latter, this list follows the decisions of the Odonata Records Committee.

The list is split into two groups: damselflies (suborder Zygoptera) and other dragonflies (infraorder Anisoptera). Those groups are organized in Families and then Genera and Species.
