''Albertosuchus'' is an extinct genus of crocodyloid crocodylian from the Late Cretaceous of Canada. The type species ''Albertosuchus knudsenii'' was named in 2015 from the Scollard Formation in Alberta. ''Albertosuchus'' is the northernmost-known Late Cretaceous crocodylian in North America. ''Albertosuchus'' lacks the notch in the upper jaw between the maxilla and premaxilla bones that is characteristic of most crocodyloids, and it also has a very short mandibular symphysis (the connection between the two halves of the lower jaw). Phylogenetic analysis indicates that it is one of the most basal members of Crocodyloidea and a close relative of ''Arenysuchus'' from the Late Cretaceous of Spain, although the incomplete nature of known material makes these findings uncertain. ==References==
