Palaealectoris is an extinct monotypic genus of landfowl, belonging to the family Tetraonidae, distantly related with modern grouses.

[1] The first remains associated with the genus, a fragmentary tibiotarsus, were collected in May 1925 in marine strata belonging to the Miocene-aged Calvert Formation, near Chesapeake Beach, Maryland, by Remington Kellogg and Norman Boss.

The holotype remains of Palaealectoris were collected during the summer of 1928 by Erich Maren Schlaikjer in Lower Miocene deposits belonging to the Agate Fossil Beds in Sioux County, Nebraska.

The genus was first described shortly after, in 1930, by Alexander Wetmore, at Schlaikjer's demandn, based on the two extremities of a left humerus, with P. incertus as the type species.

[1] The fragmentary tibiotarsus from the Calvert Formation associated with the genus was distinctly similar, although smaller, with that of the modern spruce grouse.
