Parasuchus was named by Lydekker (1885). It is not extant. It was considered monophyletic by Nesbitt (2011) and Kammerer et al. (2016).

It was considered a nomen dubium by Long and Murry (1995).

It was assigned to Mystriosuchidea by Huene (1922); to Parasuchinae by Chatterjee (1978); to Phytosauridae by Carroll (1988); to Parasuchia by Sereno (1991); to Phytosauria by Nesbitt (2011) and Stocker and Butler (2013); and to Parasuchidae by Kammerer et al. (2016).
