How to Recover a Deleted Branch in Git

To recover a deleted local branch, use git reflog to find the commit hash, then recreate the branch with git checkout -b <branch-name> <commit-hash>; 2. To restore a deleted remote branch, check for existing remote-tracking references with git branch -r, recreate the branch locally, and push it back to remote or push the commit directly using git push origin :refs/heads/; 3. If the branch name is unknown, use git fsck --lost-found to find dangling commits, inspect them with git show, and create a branch at the desired commit; 4. Prevent future issues by using safe delete commands, pushing branches to remote, and implementing backup workflows—recovery is possible within ~30 days due to Git’s reflog and object retention.

How to Recover a Deleted Branch in Git

If you’ve accidentally deleted a Git branch—whether local or remote—don’t panic. As long as you know the branch name or can find its commit hash, recovery is usually possible. Here’s how to recover a deleted branch in Git.


1. Recover a Deleted Local Branch (If It Was Merged or You Know the Commit)

Even after deleting a local branch, Git keeps the commits around for a while in its object database (usually 30 days by default) via the reflog. You can use this to restore the branch.

Steps:

  • Find the branch’s last commit using reflog:

    git reflog

    Look through the output for commits associated with the deleted branch. You’ll see entries like:

    abc1234 HEAD@{2}: checkout: moving from feature-login to main

    This means abc1234 was the tip of feature-login before switching.

  • Alternatively, if you remember the branch name, filter the reflog:

    git reflog | grep <branch-name>
  • Recreate the branch at that commit:

    git checkout -b <branch-name> <commit-hash>

    Example:

    git checkout -b feature-login abc1234

Now your branch is restored.

? Tip: You can also use git log --oneline --all --graph to visually locate lost commits if you're unsure of the hash.


2. Restore a Deleted Remote Branch

If someone deleted a remote branch (e.g., origin/feature-x), but you had it checked out locally before, your local repository may still have the reference.

Check for Stale Remote Tracking Branches:

git branch -r --contains <commit-or-branch-name>

Or list all remote-tracking branches:

git branch -r

If you see something like origin/feature-x, even if it’s gone on the server, you can re-create it locally:

git checkout -b feature-x origin/feature-x

Then push it back:

git push origin feature-x

If no local reference exists, but you know the commit hash, push it directly:

git push origin <commit-hash>:refs/heads/feature-x

3. What If You Don’t Remember the Branch Name?

Use git fsck to find dangling commits (unreferenced ones):

git fsck --lost-found

This lists dangling commits. Review them:

git show <commit-hash>

Look for familiar messages or changes.

Once you find the right commit, create a new branch:

git checkout -b recovered-branch <commit-hash>

?? Note: fsck shows all unreferenced objects—use git show to inspect and verify.


4. Prevent Future Accidents

  • Double-check before deleting:

    git branch -d <branch-name>  # safer: only deletes merged branches
    git branch -D <branch-name>  # force delete (use carefully)
  • Push important branches to remote as backup.

  • Use descriptive branch names so they’re easier to track later.

  • Consider setting up Git hooks or team workflows that require confirmation before deleting shared branches.


Recovering a deleted Git branch is usually doable thanks to Git’s built-in safety nets like reflog and object persistence. The key is acting before garbage collection runs (which typically happens after 30 days). As long as the commit isn’t truly garbage-collected, you’ve got a good chance.

Basically: act fast, use reflog, and don’t delete branches without a backup plan.
