+## Retry failed runs
+
+You can retry an individual failed run from the **Runs** tab, or retry every failed run across your active workflows in one action.
+
+To retry all failed runs:
+
+1. Go to the [Workflow Runs](https://app.mintlify.com/products/workflows) page in your dashboard.
+2. Click **Retry failed runs**.
+
+Mintlify queues the retries in the background and returns immediately. Only runs from the last 30 days on currently active workflows are eligible. To limit a retry to specific workflows, filter the page by those workflows before clicking **Retry failed runs**.
+
+<Note>
+  Mintlify automatically deduplicates retries so the same run is not queued twice. For scheduled and merge-style workflows, only the latest failed run in a group is retried.
