Leptosuchomorpha is a clade of phytosaurs. It is a node-based taxon defined by Michelle R. Stocker in 2010 as the last common ancestor of Leptosuchus studeri and Pseudopalatus pristinus and all of its descendants. A new definition was proposed by Andrew S. Jones and Richard J. Butler in 2018 as the last common ancestor and all descendants of Smilosuchus lithodendrorum, Leptosuchus studeri, and Machaeroprosopus pristinus to reflect the new interrelationships of Phytosauria they recovered.
