# JobClient.cancel

```python theme={"system"}
def JobClient.cancel(job_or_id: Job | str)

Tasks that are already being executed will finish their execution and not be interrupted. All sub-tasks spawned from such tasks after the cancellation will not be picked up by task runners.

## Parameters

  The job or job id to cancel.
</ParamField>
