讼费，是指为法庭诉讼聆讯所支出的费用，包括法院收费、法律费用、代垫付费用、杂项开支及酬金。

而讼费要经法庭评定后由决定由那一方去支付，通常获判给讼费的一方称为收取方，而须缴付讼费的一方则称为支付方。有关讼费评定，可见讼费评定一栏。

Court costs (also called law-costs) are the costs of handling a case, which, depending on legal rules, may or may not include the costs of the various parties in a lawsuit in addition to the costs of the court itself. In the United States, "court costs" (such as filing fees, copying and postage) are differentiated from attorney's fees, which are the hourly rates paid to attorneys for their work in a case. Court costs can reach very high amounts, often far beyond the actual monetary worth of a case. Cases are known in which one party won the case, but lost more than the monetary worth in court costs. Court costs may be 'awarded' to one or both parties in a lawsuit, or they may be waived.
