The crown lands, crown estate, royal domain or domaine royal of France were the lands, fiefs and rights directly possessed by the kings of France. While the term eventually came to refer to a territorial unit, the royal domain originally referred to the network of "castles, villages and estates, forests, towns, religious houses and bishoprics, and the rights of justice, tolls and taxes" effectively held by the king or under his domination. In terms of territory, before the reign of Henry IV, the domaine royal did not encompass the entirety of the territory of the kingdom of France and for much of the Middle Ages significant portions of the kingdom were the direct possessions of other feudal lords.

The Capetian dynasty, also known as the "House of France", is a dynasty of European origin, and a branch of the Robertians and the Karlings. It is among the largest and oldest royal houses in Europe and the world, and consists of Hugh Capet, the founder of the dynasty, and his male-line descendants, who ruled in France without interruption from 987 to 1792, and again from 1814 to 1848. The senior line ruled in France as the House of Capet from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, the Houses of Valois and then Bourbon, which ruled without interruption until the French Revolution abolished the monarchy in 1792. The Bourbons were restored in 1814 in the aftermath of Napoleon's defeat, but had to vacate the throne again in 1830 in favour of the last Capetian monarch of France, Louis Philippe I, who belonged to the House of Orléans. Cadet branches of the Capetian House of Bourbon are still reigning over Spain and Luxembourg.
