The New Otani Art Museum (ニューオータニ美術館) is an art museum founded in 1991 and housed on the sixth floor of the Hotel New Otani's Garden Court () office building. The Hotel, located in Tokyo's Chiyoda Ward, opened in 1964 to coincide with the Tokyo Olympic Games.
The museum's collections consist primarily of modern art from France and Japan, along with a considerable number of pieces of Japanese ukiyo-e art.
Yoneichi Otani, son of Hotel founder Yonetaro Otani, was the first director of the museum, and continues to hold that position today.
