Andalgalornis was a genus of giant flightless predatory birds of the family Phorusrhacidae or "terror birds" that lived in Argentina and contained the single species A. steulleti.
It is known from an incomplete skeleton and some single bones found in the Late Miocene to Early Pliocene Andalgala Formation of sites in the Entre Ríos and Catamarca Provinces of NE and NW Argentina. (Chiquimil) Provinces.
The birds stood around one and a half meters tall. The subfamily to which the genus belonged, the Patagornithinae, contained species that were of quite slender build; it looked much like a more elegant and smaller Phorusrhacos, but had a proportionally higher beak, the most massive in regards to the overall size of the bird of all phorusrhacids.
