Liddle Kiddles were dolls originally produced by toymakers Mattel Inc. in 1965. They were introduced at the 1966 New York Toy Fair and put on the market soon after. Initially about 3 inches tall, they were tiny by doll standards. The sensation they created in the toy world caused other toy companies to produce their own tiny dolls.

Mattel founder Elliot Handler oversaw the project. He told engineers and sculptors that he wanted the dolls to resemble little children in neighborhoods across America. Martha Armstrong-Hand, the famous doll sculptor at Mattel, made the first Kiddles in 1965. She explained that the first set of ten dolls used only three different head molds but had different hairstyles and face paint.
