Which coffeehouse chain uses a green two-tailed siren as its logo?

The coffeehouse chain that uses a green two-tailed siren as its logo is Starbucks.

Starbucks introduced its first logo in 1971, featuring a stylized two-tailed mermaid, or siren, surrounded by the company name. The image was inspired by maritime imagery and reflected Starbucks’ early identity as a Seattle coffee company connected to the Pacific Northwest’s seafaring culture.

The logo changed several times. In 1987, Starbucks changed the original brown design to green and refined the siren’s appearance. Later versions made the figure more modest and visually simplified. In 2011, the company removed the surrounding wordmark, leaving the enlarged green siren as the standalone symbol.

A common mix-up is calling the figure simply a mermaid. Starbucks officially describes her as a siren, a mythological creature associated with alluring songs. The twin tails are the distinctive feature that separates this logo from an ordinary mermaid illustration.
