Kiddles were dolls originally produced by toymaker 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. The dolls were designed to have a close resemblance to little children in neighborhoods across America. Martha Armstrong-Hand at Mattel made the first Kiddles in 1965. The first set of ten dolls in a premier series called "Liddle Kiddles" used only four different head moulds (3 of which were sculpted by Martha and 1 sculpted by another artist) but had different hairstyles and face paint. Martha Armstrong-Hand also sculpted other Mattel dolls, such as Drowsy (1965), Baby First Step (1965) and Cheerful Tearful (1966).

An accessory introduced in 1968 was the Liddle Kiddle Talking Town House, which had one of the Mattel talking voice units inside. When the "chatty-ring" was pulled one of 8 different phrases could be heard, such as "This is where the Liddle Kiddles live!". The voice unit was the same one that had been introduced in 1960 inside Mattel's Chatty Cathy doll and used in all other Mattel talking dolls and toys.
