Louis V, also known as Louis the Do-Nothing, was a king of West Francia from 979 to his early death in 987. During his reign, the nobility essentially ruled the country. Dying childless, Louis V was the last Carolingian monarch in West Francia.

In medieval historiography, West Francia or the Kingdom of the West Franks constitutes the initial stage of the Kingdom of France and extends from the year 843, from the Treaty of Verdun, to 987, the beginning of the Capetian dynasty. It was created from the division of the Carolingian Empire following the death of Louis the Pious, with its neighbor East Francia eventually evolving into the Kingdom of Germany.
