Paul Friedrich August Renner (August 9, 1878 – April 25, 1956) was a German typeface designer.

In 1927, he designed the Futura typeface, which became one of the most successful and most-used types of the 20th century.

Renner had a strict Protestant upbringing, being educated in a 19th-century Gymnasium. He was brought up to have a very German sense of leadership, of duty and responsibility. He was suspicious of abstract art and disliked many forms of modern culture, such as jazz, cinema, and dancing. But equally, he admired the functionalist strain in modernism. Thus, Renner can be seen as a bridge between the traditional (19th century) and the modern (20th century). He attempted to fuse the Gothic and the roman typefaces.

Renner was a prominent member of the Deutscher Werkbund (German Work Federation). Two of his major texts are Typografie als Kunst (Typography as Art) and Die Kunst der Typographie (The Art of Typography). He created a new set of guidelines for good book design and invented the popular Futura, a geometric sans-serif font used by many typographers throughout the 20th century and today. The typeface Architype Renner is based upon Renner’s early experimental exploration of geometric letterforms for the Futura typeface, most of which were deleted from the face’s character set before it was issued. Tasse, a 1994 typeface is a revival of Renner’s 1953 typeface Steile Futura.

Renner was a friend of the eminent German typographer Jan Tschichold and a key participant in the heated ideological and artistic debates of that time.
