In the Google Cloud console, go to the **Clusters** page.\n\n [Go to Clusters](https://console.cloud.google.com/alloydb/clusters)\n2. Click a cluster in the **Resource Name** column.\n3. In the **Overview** page, go to the **Instances in your cluster** section, choose the instance that you want to delete, and click **Delete**.\n4. In the dialog that appears, enter the instance's ID, and click **Delete**.\n\n### gcloud\n\nTo use the gcloud CLI, you can\n[install and initialize](/sdk/docs/install) the Google Cloud CLI, or you\ncan use [Cloud Shell](/shell/docs/using-cloud-shell).\n\nUse the `instances delete` command to delete an instance. \n\n```\ngcloud alloydb instances delete INSTANCE_ID \\\n --region=REGION_ID \\\n --cluster=CLUSTER_ID \\\n --project=PROJECT_ID\n```\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: The ID of the instance.\n- \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: The region where the instance is placed.\n- \u003cvar translate=\"no\"\u003eCLUSTER_ID\u003c/var\u003e: The ID of the cluster where the instance is placed.\n- \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e: The ID of the project where the cluster is placed."]]
