Zulmasuchus (meaning "Zulma Gasparini's crocodile") is an extinct genus of sebecid sebecosuchian mesoeucrocodylian. Its fossils have been found in Early Paleocene-age rocks (Danian stage) of the Santa Lucia Formation in Bolivia. Zulmasuchus was named in 2007 by Alfredo Paolillo and Omar Linares for fossils originally described by Buffetaut and Marshall in 1991 as Sebecus querejazus. Thus, the type species is Z. querejazus.
