The Caslon type foundry was a type foundry in London which cast and sold metal type. It was founded by the punchcutter and typefounder William Caslon I, probably in 1720. For most of its history it was based at Chiswell Street, Islington, was the oldest type foundry in London, and the most prestigious.

Punchcutting is a craft used in traditional typography to cut letter punches in steel as the first stage of making metal type. Steel punches in the shape of the letter would be used to stamp matrices into copper, which were locked into a mould shape to cast type. Cutting punches and casting type was the first step of traditional typesetting. The cutting of letter punches was a highly skilled craft requiring much patience and practice. Often the designer of the type would not be personally involved in the cutting.
