Lansquenet is a banking game played with cards, named after the French spelling of the German word Landsknecht ('servant of the land or country'), which refers to 15th- and 16th-century German mercenary foot soldiers; the lansquenet drum is a type of field drum used by these soldiers.

When jumelle (twins), or the turning up of similar cards on both sides, occurs, then the dealer takes half the stake.

Lucien Debray imagines Baroness Danglers might occupy herself with lansquenet in the Dumas novel The Count of Monte Cristo.

Lansquenet is played by various characters in the Pierre Choderlos de Laclos novel Les Liaisons dangereuses.

For example, in Chapter Thirteen of "The Masqueraders", Lansquenet is played in the novel The Luck of Barry Lyndon by William Makepeace Thackeray.
