# DeleteDataset


**Note**  
This operation applies only to Amazon Rekognition Custom Labels.

Deletes an existing Amazon Rekognition Custom Labels dataset. Deleting a dataset might take while. Use [DescribeDataset](API_DescribeDataset.md) to check the current status. The dataset is still deleting if the value of `Status` is `DELETE_IN_PROGRESS`. If you try to access the dataset after it is deleted, you get a `ResourceNotFoundException` exception. 

You can't delete a dataset while it is creating (`Status` = `CREATE_IN_PROGRESS`) or if the dataset is updating (`Status` = `UPDATE_IN_PROGRESS`).

This operation requires permissions to perform the `rekognition:DeleteDataset` action.
