Patience (Europe), card solitaire or solitaire (US/Canada), is a genre of card games whose common feature is that the aim is to arrange the cards in some systematic order or, in a few cases, to pair them off in order to discard them. Most are intended for play by a singleplayer, but there are also "excellent games of patience for two or more players".

Patience is probably of German or Scandinavian origin, the earliest records appearing in there in the late 1700s and early 1800s. The game became popular in France in the early 19th century, reaching Britain and America in the latter half. The earliest known description of a game of patience appeared in the 1783 edition of the German game anthology Das neue Königliche L'Hombre-Spiel, where it is called Patience and describes a game between two players playing alternately. Before this, there were no literary mentions of such games in large game compendia such as Charles Cotton's The Compleat Gamester (1674) and Abbé Bellecour's Academie des Jeux (1674). Books were also reported to appear in Sweden and Russia in the early 1800s and the earliest book of patience games was published in Russia in 1826. More followed, especially in Sweden. There are additional references to Patience in French literature.
