Li Dong (李东, ?–?) was a Southern Song dynasty genre painter whose dates of birth and death are unknown. During the reign of Emperor Lizong, he often sold his paintings on the imperial street in Lin'an (present-day Hangzhou), and frequently produced works depicting the joys of village life.

His works were influenced by academy-style painting and followed the methods of Ma Yuan and Xia Gui, featuring concise and vigorous brushwork and distinctive compositions rich in a strong flavor of folk life. Selling Fish on a Snowy River is his only surviving work.
