How to hide my friend list on facebook

By default, everyone can see the Friends section of your profile. To adjust who can see your Friends section:

1. Go to your profile
2. Click Friends below your cover photo
3. Click  at the top of the page and select Edit Privacy from the dropdown menu
4. Select an audience (ex: Friends, Public) to choose who you share your friend list with on your profile

Note: People may see mutual friends when they visit your profile. Your friends also control who can see their friendships on their own profiles. If people can see your friendship on another profile, they'll also be able to see it in News Feed, search and other places on Facebook.
