+# Rename A Remote
+
+If you just added a remote (`git remote add ...`) and messed up the name or
+just need to rename some existing remote, you can do so with the `rename`
+command.
+
+First, let's see the remotes we have:
+
+```bash
+$ git remote -v
+origin  https://github.com/jbranchaud/til.git (fetch)
+origin  https://github.com/jbranchaud/til.git (push)
+```
+
+To then rename `origin` to `destination`, for example, we can issue the
+following command:
+
+```bash
+$ git remote rename origin destination
+```
+
+See `man git-remote` for more details.
