Unenlagiidae is a proposed family of eumaniraptoran paravians that includes the subfamilies Unenlagiinae and possibly Halszkaraptorinae.

However, since the 2010s, there have been subsequent studies that have questioned this placement, necessitating the revival of the family name.

Some have placed unenlagiids as outside Dromaeosauridae, being the sister taxon or closely related to Avialae,[2][3] while others have placed the newly recognized halszkaraptorines in the family, as basal deinonychosaurs outside Dromaeosauridae and Troodontidae.

[4] Other recent studies supported the traditional placement of Halszkaraptorinae and Unenlagiinae in Dromaeosauridae, forming no distinct clade.
