Viator picis is an extinct genus and species of lapwing (Charadriiformes; Charadriidae; Vanellinae) known only from the upper Pleistoceneasphalt deposits known as the Talara Tar Seeps, which are found near Talara, northwestern Peru. It was described by Campbell (1979). Although it appears to be related to the southern lapwing (Belonopterus chilensis) and the Andean lapwing (Belonopterus resplendens), it is quite distinct from Vanellussensu stricto; however, most authorities now include the former two species in an expanded Vanellus which includes all lapwings, in which case Viator picis may belong in Vanellus as well.
