Lambertianic acid is a naturally occurring organic compound classified as a diterpenoid with the molecular formula C₂₀H₂₈O₃. This is a tricyclic carboxylic acid first isolated from the oleoresin of the Lambert pine (Pinus lambertiana), from which it derives its name. The acid is a member of the abietane family of diterpenes, characterized by its aromatic C-ring.
