The term "bar fine" (sometimes shortened to "barfine") is used to refer to the payment made to the operators of a bar to allow an employee (typically a dancer or hostess) of the bar to leave work early to accompany the customer. This is typically part of a form of prostitution typical in some countries where it is commonly tolerated or legal, including Thailand and the Philippines.

In areas where this form of prostitution is common, paying an employee's bar fine may or may not include payment for sexual services. For example, a typical bar fine in red light districts in Thailand (such as Nana Plaza or those found in Pattaya) is 500-600 Thai baht and does not include payment for sexual services which must be negotiated separately with the employee being bar fined. In some other areas, such as the red light districts around Fields Avenue in Angeles City in the Philippines the barfine will typically be "all-inclusive".
