Chop suey (杂碎; lit. mixed broken pieces) is a dish in the style of Chinese cuisine, which was said to be invented in New York on August 29, 1896 by cooks of the Chinese diplomat Li Hung-Chang.

It is mostly a vegetable dish, with bits of beef or pork. Typical ingredients for chop suey are usually local vegetables, but tend to include: bok choy, broccoli, bamboo shoots, mushrooms, water chestnuts, green pepper, celery, onion, and snow peas.

It is not an authentic Chinese dish, and is considered typical American Chinese cuisine to the point of being the topic of a song in the musical Flower Drum Song.
