Street prostitution is a form of sex work in which a sex worker solicits customers from a public place, most commonly a street, while waiting at street corners or walking alongside a street, but also other public places such as parks, benches, etc. The street prostitute is often dressed in a provocative manner. The sex act may be performed in the customer's car, in a nearby secluded street location, or at the prostitute's residence or in a rented motel room.

A kerb crawler (or curb crawler) is a person who drives around areas known for street prostitution soliciting prostitutes for sexual activity. The act is known as "kerb crawling" because the person will typically drive very slowly along the kerbside.

Where prostitution is illegal, kerb crawlers are widely regarded as a public nuisance: they help keep street prostitutes in business in red-light districts and often solicit pedestrians who are not prostitutes for sex. As a result, kerb-crawling is illegal in many jurisdictions.
