Didone is a typeface classification recognized by the Association Typographique Internationale (AtypI). It is characterized by slab-like serifs without brackets, vertical orientation of weight axes, strong contrast between thick and thin lines, and an unornamented, "modern" appearance.

Examples include the slightly condensed, unbracketed serif typefaces Bodoni, Computer Modern, Didot, and Walbaum. The classification is also known as modern. This style emerged in the late 18th century; Didot was its first representative.
