Titanacris is a genus of large grasshoppers in the subfamily Romaleinae and tribe Tropidacrini. They are found from southeastern Mexico, through Central and South America, ranging south to northernmost Argentina.{{cite journal| last=Descamps | first=M. | last2=Carbonell | first2=C.S. | year=1985 | title=Revision of the Neotropical Arboreal Genus Titanacris (Orthoptera, Acridoidea, Romaleidae). | journal=Annales de la Société entomologique de France | volume=21 | issue=3 | pages=259-285 | doi=10.1080/21686351.1985.12278760 }}

Adult males are generally {{cvt|5-9|cm}} long and females {{cvt|7-13|cm}} long, but they are quite poorly known because they live high in the canopy of tropical forests, they are excellent fliers (not easily caught), and only T. albipes and T. velazquezii appear to regularly be attracted to artificial light at night. They are mostly green, but in flight they have conspicuously violet, red, orange-red or pink wings; their wings lack the dark rear edge and spotting seen in the closely related Tropidacris. The shape of the female's ovipositor indicates that the eggs are deposited in the soil, similar to the better-known Tropidacris.
