“Moustache” is the traditional British English spelling, while “mustache” is the American English spelling. Both refer to the facial hair that grows on the upper lip.
Have you ever typed moustache in a document only to have your spell checker suggest mustache? Or perhaps you saw both spellings online and wondered if one was wrong.

Understanding the distinction can help you write more naturally for your audience and avoid inconsistencies in professional documents, websites, academic papers, and social media posts. If you are writing for readers in the United States, the United Kingdom, Canada, Australia, or a global audience, knowing which spelling to choose is useful.
In this guide, you’ll learn the origins of both words, how they differ across English-speaking regions, common mistakes people make, and which spelling is best for your specific audience.
