Harbour and harbor are both correct spellings, but “harbour” is standard in British English while “harbor” is standard in American English. The two words have the same meaning and refer to a sheltered place where ships and boats can stay safely. People often search for “harbour or harbor” because the spelling changes between major forms of English.

The Origin of Harbour or Harbor
The word has a long history in English.
Harbour comes from older Germanic language forms related to a place of shelter or lodging. Middle English developed forms such as herber and herberwe, which were influenced by Old English and Old Norse vocabulary.
Over time, the word developed into the modern English harbour.
Why Does American English Use Harbor?
The spelling harbor became standard in American English as spelling conventions developed in the United States.
American English often simplified certain words ending in -our by removing the u.
This created pairs such as:
| British English | American English |
| harbour | harbor |
| colour | color |
| favour | favor |
| honour | honor |
| labour | labor |
The pronunciation and basic meanings usually remain the same.
Is One Spelling Older?

Related British and American Spelling Patterns
The same pattern appears in several common words:

However, not every word ending in -our follows exactly the same pattern, so writers should check less common words when unsure.
