A share of common stock that is required to be held by a candidate for a board of directors (BOD) in order to qualify as a director of the issuing company. This share has the same properties of common shares held by other shareholders. However, it constitutes a requirement of holding a vested interest in the company in the form of common stock.

Qualifying share may also refer to a share that was issued, in Canada, by a corporation (known as qualifying corporation) after May 22, 1985 and before 1987.
