Valentine (1832) was a novel published by French author George Sand.
 This was the second novel published in Sand's career as an independent author, the novel is notable for displaying many of Sand's preoccupations as an emerging novelist: love, social class, greed, liberty, and family ties.
 Like many of Sand's novels, the novel takes its name from its title character Valentine, who is born into an aristocratic family but falls in love with the peasant farmer, Benedict.
 Star-crossed lovers belonging to different social classes were to become a major theme in Sand's works, which interrogated what the author perceived as the hypocrisy and rigidity of social norms in the Restoration-period French republic.
