Which McDonald’s restaurant branding element became known as the “M” logo?

The Golden Arches became known as McDonald’s “M” logo.

The symbol originated in the large yellow arches used in the design of McDonald’s restaurants during the 1950s. Their height made the buildings visible to passing motorists, an important feature for a growing roadside restaurant chain.

In 1962, designer Jim Schindler combined the two architectural arches into a stylized graphic mark. The resulting form resembled the letter M and became McDonald’s principal visual identifier. It could work on signs, packaging and advertising without requiring the full company name.

The Golden Arches are sometimes described as merely a typeface or a letterform created from scratch. Their distinctive branding power comes from the connection between the graphic logo and the earlier restaurant architecture. The mark’s yellow color and simple shape helped make it recognizable across languages and national markets.
