Tip: If you want to cancel your paid subscription, you can downgrade your organization to GitHub Free instead of deleting the organization and its content.
Once you delete an organization, GitHub cannot restore your content. Therefore, before you delete your organization, make sure you have a copy of all repositories, wikis, issues, and project boards from the account.
- In the top right corner of GitHub, click your profile photo, then click Your organizations.
- Click Settings next to the organization.
- Near the bottom of the organization's settings page, click Delete this Organization.
