# POST /#Action=CreateDBCluster

`POST /#Action=CreateDBCluster`

Creates a new Amazon Neptune DB cluster.

You can use the `ReplicationSourceIdentifier` parameter to create the DB cluster as a Read Replica of another DB cluster or Amazon Neptune DB instance.

Note that when you create a new cluster using `CreateDBCluster` directly, deletion protection is disabled by default (when you create a new production cluster in the console, deletion protection is enabled by default). You can only delete a DB cluster if its `DeletionProtection` field is set to `false`.
