Sphinx libocedrus, the incense cedar sphinx, is a moth of the family Sphingidae. The species was first described by Henry Edwards in 1881. It ranges from the western Texas to southern California and Mexico. The wingspan is 70–80 mm. The upperside of the forewing is pale blue gray to dark gray with a black dash reaching the wing tip and a white stripe along the lower outer margin. The upperside of the hindwing is black with two diffuse white bands. There is one generation with adults on wing from July to September. The larvae feed on New Mexican forestiera (Forestiera neomexicana), Forestiera angustifolia and Fraxinus gooddingii in the olive family (Oleaceae).
