Go to the SharePoint site you want to delete
Select the Settings gear icon

Select Delete this site
Confirm the deletion when prompted
If you do not see the delete option, check your permissions or ask a SharePoint admin

For a SharePoint admin, use the SharePoint admin center if site deletion is managed there
