The Bài (牌) was an imperial Vietnamese decoration for merit. The decoration, an oblong shield of gold set with ten rubies, was worn on a cord around the neck. It was given to princes, mandarins, generals, ministers and the highest civil servants.

The decoration is very old^{[citation needed]} but was reformed by the emperor Thành Thái in 1889. It ceased to exist after the fall of the Vietnamese monarchy in 1945.
