The Legitimists (French: Légitimistes) are royalists who adhere to the rights of dynastic succession to the French crown of the descendants of the eldest branch of the Bourbon dynasty, which was overthrown in the 1830 July Revolution. They reject the claim of the July Monarchy of 1830–1848 which placed Louis Philippe, Duke of Orléans, head of the Orléans cadet branch of the Bourbon dynasty, on the throne until he too was dethroned and driven with his family into exile.

Following the movement of Ultra-royalists during the Bourbon Restoration of 1814, Legitimists came to form one of the three main right-wing factions in France, which was principally characterized by its counter-revolutionary views. According to historian René Rémond, the other two right-wing factions were the Orléanists and the Bonapartists.

Legitimists believe that the traditional rules of succession, based on the Salic law, determine the rightful King of France. The last ruling king whom legitimists acknowledge as legitimate was Charles X, and when the line of his heirs became extinct in 1883 with the death of his grandson Henri, Count of Chambord, the most senior heir to the throne under these traditional rules was Infante Juan, Count of Montizón, a descendant of Louis XIV through his grandson Philip V of Spain. The fact that all French Legitimist claimants since 1883 have been members of the Spanish royal dynasty, the allegation that their patrilineal descent from Louis XIV has been in question since 1936, and the belief that Philip V renounced claims to the French throne for himself and his heirs-male in the Treaty of Utrecht, are all irrelevant to Legitimism; however, these facts have prompted other French monarchists to pivot to support of the Orléans line, who would be next in the traditional line of succession if Philip's heirs were excluded, or support to the Bonaparte family.

The current Legitimist pretender is Prince Louis, Duke of Anjou, the senior great-grandson of Alfonso XIII of Spain by male primogeniture, whose line was excluded from the Spanish succession.
