The Marvelettes were an American singing girl group on the Motown label. Motown's first successful female vocal group, the Marvelettes are most notable for recording the label's first US #1 pop hit, "Please Mr. Postman", and for setting the precedent for later Motown girl groups such as Martha and the Vandellas and The Supremes.

During their eight-year run on the Billboard charts, the group scored nineteen top forty American R&B singles and ten top forty American pop singles. Of these hits, three were top ten pop singles and nine were top ten R&B singles, and one, "Please Mr. Postman," was number one on both charts.
