Lyginopteridaceae is an extinct family of plants (Pteridospermatophyta) in North America and European Carboniferous coal measures.^[2]

Lyginopteridaceae were shrubs and vines with radiospermic ovules containing a lagenostome. They consisted of forms with monostelic stem petioles usually with single strand and small seeds. Family members include Lyginopteris and Heterangium.^[3]
