Viniegra de Abajo is a municipality of La Rioja (Spain).

The finding of tombs and a Visigothic wake in the urban enclosure attests the antiquity of the foundation of the town.

In 1366 it was included with the denomination of Viniegra de Yuso, between the localities of the Lordship of Cameros, that would be yielded by Enrique II of Trastámara to Juan Ramirez de Arellano by its support in the fight against Pedro the Cruel.

Since then it belonged to the lordship of the counts of Aguilar and Inestrillas, heirs of the dominion of Cameros, according to what appears stated in the Cadastre of the Marquis of Ensenada of year 1751.

In Viniegra there are two main celebrations, those of Winter, that are those of San Ildefonso, and those of summer, Santiago.
