What is the name of McDonald's yellow M-shaped corporate symbol?

McDonald's yellow M-shaped corporate symbol is called the Golden Arches.

The Golden Arches began as architectural features on McDonald's restaurants in the 1950s. Their shape was inspired by paired arches built into the sides of early restaurant buildings, where they served as highly visible roadside markers.

By the 1960s, the arches had evolved from a building design into a recognizable corporate logo. The symbol became one of the world's most familiar examples of brand identity, often identifying McDonald's even when the company name is absent.

The term refers to the paired-arch concept, not merely to the color yellow or to the letter M. McDonald's has changed the logo's styling over time, but the arches remain the central visual element of its brand.
