不记名债券，（英语:Bearer bond），为发行公司或政府没有把债券所有人姓名登录在名册上的债券，持券人只凭息票领取利息。好处是投资者的身份保密，坏处是投资者一旦损毁或失去债券便难以证明其拥有人的身份。

A bearer bond is a bond or debt security issued by a business entity such as a corporation, or a government. It differs from the more common types of investment securities in that it is unregistered – no records are kept of the owner, or the transactions involving ownership. Whoever physically holds the paper on which the bond is issued owns the instrument. This is useful for investors who wish to retain anonymity. Recovery of the value of a bearer bond in the event of its loss, theft, or destruction is usually impossible. Some relief is possible in the case of United States public debt.
