Optima is a humanist sans-serif typeface designed by Hermann Zapf and released by the D. Stempel AG foundry, Frankfurt, West Germany in 1958.

In typography and lettering, a sans-serif, sans serif, gothic, or simply sans letterform is one that does not have extending features called "serifs" at the end of strokes. Sans-serif typefaces tend to have less stroke width variation than serif typefaces. They are often used to convey simplicity and modernity or minimalism. For the purposes of type classification, sans-serif designs are usually divided into these major groups: § Grotesque and § Neo-grotesque, § Geometric, § Humanist and § Other or mixed.
