金融信用（英语：Credit），即提供贷款和产生债务。在许多场合，金融信用也可以指借债方偿还债务的信誉和能力。信用意指一个人能够先取得金钱或是商品，日后再行付款的限度。

信用产生的另一种方式是商品交易过程中的延迟付款。在延迟期限前还清欠款，就是正面的信用纪录，所以时常欠款又还清的人反而比不曾借钱动用信用的人有更好纪录「成绩」，信用额度也更容易扩大。

如果过时限借钱不还称为违约。对象是金融机构的话，个人违约状况会被在信用局数据库注记。在多数国家，违约严重时再次向合法金融机构借款会很困难，直到协议或法庭作出判决后得到解决。 。

Credit (from Latin credit, "(he/she/it) believes") is the trust which allows one party to provide money or resources to another party where that second party does not reimburse the first party immediately (thereby generating a debt), but instead arranges either to repay or return those resources (or other materials of equal value) at a later date. The resources provided may be financial (e.g. granting a loan), or they may consist of goods or services (e.g. consumer credit). Credit encompasses any form of deferred payment. Credit is extended by a creditor, also known as a lender, to a debtor, also known as a borrower.
