Why would we want to hide a list in Sharepoint? First this could be a lookup list and you do not want random users with contribue rights to the site to add to this list. So we can hide a list in SharePoint.
First open the site in question in SharePoint Designer Double click the list folder in the Web Site view and then find your list. Right click your list and choose properties. Then on the settings tab click Hide from Browser. Save and close. You are now done.
