Keith is the correct and standard spelling of the name. Kieth is usually a misspelling or spelling error. People often search for “Keith or Kieth” when they are unsure how to spell the name, especially when writing a person’s name in an email, document, form, or social media post.
The confusion is easy to understand because Keith does not sound exactly the way its letters might suggest. The unusual order of the vowels can make Kieth look possible at first glance. However, the traditional English spelling is Keith.
The name Keith is a well established personal name with Scottish roots. It has been used for centuries and remains common in English speaking countries. Kieth, by contrast, is not the standard spelling of the name, although some people may use it as a personal spelling or family name.
If you are writing the name of someone who spells it Keith, use that exact form. Names should always be spelled according to the person’s own preference.
Keith or Kieth – Quick Answer

The Origin of Keith or Kieth
The name Keith has Scottish origins. It is connected with a place name in Scotland and became associated with the Keith family, an important historical family in Scottish history.
Over time, Keith developed from a Scottish surname into a commonly used first name. It became especially familiar in English speaking countries and is still used as a given name today.
The spelling Kieth does not represent a separate standard English form of the traditional name. Its appearance is often explained by a simple letter order mistake. Since ie and ei patterns can cause confusion in English spelling, writers may accidentally produce Kieth instead of Keith.
