A tin toy, or tin lithograph toy, is a mechanical toy made out of tinplate and colorfully painted by chromolithography to resemble primarily a character or vehicle.

Tinplate was used in the manufacture of toys beginning in the mid-19th century. The toys were made from thin sheets of steel plated with tin, hence the name tinplate. They were a cheap and durable substitute for wooden toys. The toys were originally assembled and painted by hand. Spring activated tin toys originated in Germany in the 1850s. In the late 1880s offset lithography was used to print designs on tinplate. After the colorful designs were printed on the metal, they were formed by dies and assembled with small tabs. The lightweight of the toys allowed them to be shipped less expensively and easier than the heavier cast iron toys.

Germany was the major producer of tin toys in the world in the early 20th century. The most famous German manufacturer of tin toys was Ernst Paul Lehmann who is said to have exported 90% of his toys. France and England joined the fray and it wasn't long before hundreds of thousands of these tin toys were being manufactured.
