What is the name of the McDonald's logo formed by two yellow arches?

The McDonald's logo formed by two yellow arches is called the Golden Arches.

The arches began as architectural features of McDonald's restaurants during the 1950s. The original buildings used curved yellow structures at the sides of the roof, making the restaurants visible from nearby roads. In 1962, designer Jim Schindler combined the two arches into the familiar M-shaped graphic logo.

The symbol became especially powerful because it could identify McDonald's without showing a building, menu, or product. Its simple shape and bright color made it effective on roadside signs, packaging, uniforms, and advertising. The Golden Arches are now closely associated with the company worldwide.

“Golden Arches” refers to the branding symbol, not the letter M as a generic typographic label. The M shape is part of the design, but the established name comes from the arches' architectural origin and golden-yellow appearance.
