Six Gentlemen is a landscape painting by the Yuan dynasty Chinese artist Ni Zan (1301–1374). The work portrays six trees along a riverbank, a metaphor for the principled seclusion of virtuous gentlemen in an era of violent upheaval and foreign occupation. As the first of Ni Zan’s paintings to demonstrate the stark, minimalist style for which he is known, Six Gentlemen marked a turning point in his artistic career. He would frequently return to its subject matter in later years, producing many subsequent works of nearly identical composition and style.

Ni Zan was a Chinese painter during the Yuan and early Ming periods. Along with Huang Gongwang, Wu Zhen, and Wang Meng, he is considered to be one of the Four Masters of the Yuan Dynasty.
