How do I hide my friend list?

You can hide up to 30 friends.

To do that, go to SettingsPrivacyWho is visible in my list of friends and followed users. Alternatively, follow this link: vk.com/settings?act=privacy. Your friends are listed first there, then you can find users you follow.

Don't forget to set the Who can view my hidden friends option to the appropriate setting.

You can't hide all your friends. VK is a social network and we want users to easily find people they may know on the website.
