Termopsidae is an extinct family of termites in the order Blattodea. The five extant genera formerly included in Termopsidae (Archotermopsis, Hodotermopsis, Porotermes, Stolotermes, and Zootermopsis) now belong in their own distinct families, leaving only extinct taxa in Termopsidae.

Several prehistoric genera are placed herein, known only from fossils. Since only a small part of the diversity of dampwood termites survives, it is rather difficult to assign these to subfamilies. Several seem to represent very ancient members of the family; they may be quite basal Termopsidae, so it is indeed unwarranted to place them into a subfamily at all.
