American Girl is an American line of 18-inch (46 cm) dolls released on May 5, 1986 by Pleasant Company. The dolls portray eight- to fourteen-year-old girls of various ethnicities, faiths, nationalities, and social classes throughout different time periods throughout history. They are sold with accompanying books told from the viewpoint of the girls. Originally the stories focused on various periods of American history, but were expanded to include characters and stories from contemporary life. Aside from the original American Girl dolls, buyers also have the option to purchase Truly Me dolls, which vary by eye color, face mold, skin color, hair texture, and hair length. A variety of related clothing and accessories is also available. A service for ordering a custom-made doll with features and clothing specified by the owner dubbed Create Your Own, was introduced in 2017.

A doll is a model typically of a human or humanoid character, often used as a toy for children. Dolls have also been used in traditional religious rituals throughout the world. Traditional dolls made of materials such as clay and wood are found in the Americas, Asia, Africa and Europe. The earliest documented dolls go back to the ancient civilizations of Egypt, Greece, and Rome. They have been made as crude, rudimentary playthings as well as elaborate art. Modern doll manufacturing has its roots in Germany, from the 15th century. With industrialization and new materials such as porcelain and plastic, dolls were increasingly mass-produced. During the 20th century, dolls became increasingly popular as collectibles.
