The Starbucks Siren has been the company’s symbol since 1971, but the image has changed dramatically over five decades. The original version was a surprisingly explicit depiction of a bare-breasted twin-tailed mermaid. The current logo is a clean green silhouette. Understanding this evolution — and how the current mark is legally protected — reveals a great deal about how brand identity and trademark strategy intersect.
Why a Siren?
Starbucks’s founders wanted a symbol evoking the maritime heritage of Seattle and the seductive pull of coffee. They found a 16th-century Norse woodcut depicting a twin-tailed siren and adapted it. The first logo showed the figure in full, with exposed torso and spread tails, on a brown background.
The Evolution: 1971 to Today
When Howard Schultz expanded Starbucks in 1987, he redesigned the logo: the siren was cropped to reduce exposure, and green replaced brown as the dominant color. In 1992, the image was zoomed in further, showing only the siren’s upper body. In 2011, Starbucks removed the “Starbucks Coffee” text entirely, leaving only the siren silhouette on a green circle — the current logo.
Trademark Registration
The Starbucks siren is registered as a trademark in the US and internationally. The 2011 transition to a wordless mark was strategically significant. A mark that functions without text — that is recognizable from silhouette alone — signals a level of consumer recognition that reinforces the “famous mark” status that provides the broadest legal protection.

Enforcement Against Similar Marks
Starbucks has been aggressive in challenging brands that use mermaid or siren imagery, particularly those that combine such imagery with a green circular background. Critics note that some enforcement actions have targeted very small businesses with no real prospect of consumer confusion. The company’s position is that consistent enforcement is necessary to prevent dilution of the mark.
Removing the Text: A Strategic Statement
The 2011 decision to drop the wordmark is the element I find most interesting. It was not merely a design simplification. It was a declaration: our symbol is recognizable without our name. This is the standard achieved by the Coca-Cola Dynamic Ribbon, the Apple logo, and Nike’s Swoosh. A mark that needs no text to identify its source has reached the apex of trademark recognition — and, correspondingly, the apex of trademark protection.
