# Use `DeleteAlias` with an AWS SDK or CLI
<a name="kms_example_kms_DeleteAlias_section"></a>

The following code examples show how to use `DeleteAlias`.

------
#### [ CLI ]

**AWS CLI**  
**To delete an AWS KMS alias**  
The following `delete-alias` example deletes the alias `alias/example-alias`. The alias name must begin with alias/.  

```
aws kms delete-alias \
    --alias-name alias/example-alias
```
This command produces no output. To find the alias, use the `list-aliases` command.  
For more information, see [Deleting an alias](https://docs.aws.amazon.com/kms/latest/developerguide/alias-manage.html#alias-delete) in the *AWS Key Management Service Developer Guide*.  
+  For API details, see [DeleteAlias](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/kms/delete-alias.html) in *AWS CLI Command Reference*.

        return getAsyncClient().deleteAlias(deleteAliasRequest)
            .thenRun(() -> {
                logger.info("Alias {} has been deleted successfully", aliasName);
