零息票债券（zero coupon bond）是不支付利息的债券，通常在到期日按面值支付给债券持有人。投资者通过以债券面值的折扣价买入来获利。这类债券可以在发行时加入折扣，或由一家银行除去息票，然后包装成为零息票债券发行。

常见的零息票债券如美国的短期国债，以及交易商将普通的长期债券的利息和本金进行拆分而得到的多个零息票债券，被称作strip bonds。（反之，多个零息票债券也可以组合成与普通的长期债券相同的现金流。无套利定价理论保证了两者的价值应该非常接近。）美国财政部自1985年起发行把中长期国债拆分得到的STRIPS（Separate Trading of Registered Interest and Principal of Securities，注册的证券本金和利息的分离交易）。

A zero-coupon bond (also discount bond or deep discount bond) is a bond bought at a price lower than its face value, with the face value repaid at the time of maturity. Note that this definition assumes a positive time value of money. It does not make periodic interest payments, or have so-called "coupons", hence the term zero-coupon bond. When the bond reaches maturity, its investor receives its par (or face) value. Examples of zero-coupon bonds include U.S. Treasury bills, U.S. savings bonds, long-term zero-coupon bonds, and any type of coupon bond that has been stripped of its coupons.
