Procuring or pandering is the facilitation or provision of a prostitute or other sex worker in the arrangement of a sex act with a customer. A procurer, colloquially called a pimp (if male) or a madam (if female, though the term pimp has still extensively been used for female procurers as well) or a brothel keeper, is an agent for prostitutes who collects part of their earnings. The procurer may receive this money in return for advertising services, physical protection, or for providing and possibly monopolizing a location where the prostitute may solicit clients. Like prostitution, the legality of certain actions of a madam or a pimp vary from one region to the next.

Examples of procuring include:

• Trafficking a person into a country for the purpose of soliciting sex
• Operating a business where prostitution occurs
• Transporting a prostitute to the location of their arrangement
• Deriving financial gain from the prostitution of another
