Tip
If you opened a pull request with the wrong base branch, instead of closing it and opening a new one, you can change the base branch. See Changing the base branch of a pull request.
- Under your repository name, click Pull requests.
- In the "Pull Requests" list, click the pull request you want to close.
- At the bottom of the pull request, below the comment box, click Close pull request.
- Optionally, delete the branch. This keeps the list of branches in your repository tidy.
