Comptonia peregrina is a species of flowering plant in the family Myricaceae native to eastern North America.

Compare the plant's Quebec French name, comptonie voyageuse: "traveling comptonia."

[6] In 1789, Charles Louis L'Héritier placed Linnaeus's original Myrica aspleniifolia in his new genus Comptonia.

[3] Comptonia peregrina is used as a food plant by the larvae of some Lepidoptera species, including Bucculatrix paroptila, grey pug, setaceous Hebrew character, Io moth, and several Coleophora case-bearers: C. comptoniella, C. peregrinaevorella (which feeds exclusively on Comptonia), C. persimplexella, C. pruniella and C. serratella.

The Canadian author Catharine Parr Traill includes it in her book The Female Emigrant's Guide in a list of substitutes for China tea.

"[10] Tea made from the plant has been said to treat the effects of poison ivy when applied to the affected area.
