Philip V (Spanish: Felipe V; French: Philippe de France; 19 December 1683 – 9 July 1746) is King of Spain from 1 November 1700 to 15 January 1724, when he abdicates in favor of his son Louis, and from 6 September 1724, when he assumes the throne again upon his son's death, to his death.

Before his reign, Philip occupies an exalted place in the royal family of France as a grandson of King Louis XIV.

His father, Louis, the Grand Dauphin, has the strongest genealogical claim to the throne of Spain when it becomes vacant in 1700.

However, since the Grand Dauphin and Philip's older brother, Louis, Duke of Burgundy, cannot be displaced from their place in the succession to the French throne, King Charles II of Spain names Philip as his heir in his will.

It is well known that the union of France and Spain under one monarch would upset the balance of power in Europe, such that other European powers would take steps to prevent it.

Philip is the first member of the House of Bourbon to rule as king of Spain.

The sum of his two reigns, 45 years and 21 days, is the longest in modern Spanish history.
