+#### Delete a stopped environment
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/22629) in GitLab 12.9.
+
+You can delete [stopped environments](#stopping-an-environment) in one of two
+ways: through the GitLab UI or through the API.
+
+##### Delete environments through the UI
+
+To view the list of **Stopped** environments, navigate to **Operations > Environments**
+and click the **Stopped** tab.
+
+From there, you can click the **Delete** button directly, or you can click the
+environment name to see its details and **Delete** it from there.
+
+You can also delete environments by viewing the details for a
+stopped environment:
+
+  1. Navigate to **Operations > Environments**.
+  1. Click on the name of an environment within the **Stopped** environments list.
+  1. Click on the **Delete** button that appears at the top for all stopped environments.
+  1. Finally, confirm your chosen environment in the modal that appears to delete it.
+
+##### Delete environments through the API
+
+Environments can also be deleted by using the [Environments API](../api/environments.md#delete-an-environment).
+
