吉尔伯特·查尔斯·斯图尔特，美国罗得岛州画家。

吉尔伯特·斯图尔特（1755年12月3日－1828年7月9日）被认为是美国最著名的肖像画家之一。他最出名的作品，一幅未完成的乔治·华盛顿肖像（有时称作The Athenaeum），该作品于1796年开工，但由于吉尔伯特1828年去世而未能完成。这幅肖像在美国一元纸币上躺了一个世纪。

终其一生，吉尔伯特为1000多人画了肖像，包括6位美国总统。他的作品现在多收藏于美国和英国的博物馆，尤其是纽约的大都会博物馆和Frick Collection，华盛顿的美国国家艺廊，伦敦的国家肖像馆和波士顿的美术馆。

Gilbert Charles Stuart (born Stewart; December 3, 1755 – July 9, 1828) was an American painter from Rhode Island.

Gilbert Stuart is widely considered one of America's foremost portraitists. His best known work, the unfinished portrait of George Washington that is sometimes referred to as The Athenaeum, was begun in 1796 and never finished; Stuart retained the portrait and used it to paint 130 copies which he sold for $100 each. The image of George Washington featured in the painting has appeared on the United States one-dollar bill for over a century, and on various U.S. Postage stamps of the 19th century and early 20th century.
