Liu Ling (劉陵) (died 122 BC or earlier) was a Han dynasty princess during Emperor Wu's reign.
She was the daughter of Liu An, the King of Huainan, as well as a second cousin of Emperor Wu.
Liu An sent her to the national capital Chang'an to become a socialite, so as to spy on Emperor Wu and his ministers.
Her father was fond of her, and sent her to Chang'an with a lot of "gold and money" to "befriend" and "spy on" the Emperor and those to his "left and right".
She bribed and had an illicit sexual relationship with at least one person: Zhang Cigong (張次公), the Marquess of Antou (岸頭侯), who lost his title and territory when the scandal was exposed in 122 BC,[2] the year Liu An and Liu Ling were executed.
