Clans, previously called guilds, are organizations of contestants that attempt to help out other members of their organization. Common ways of helping each other are by providing answers to questions about the Island, giving gifts of equipment, and spending cigs to develop clan buffs which are enormously helpful to clan members during jungle fights. If you see one of your fellow clan members in the fields, instead of attacking them, perform your own Secret Handshake correctly and you will each receive a positive buff for the rest of the day.

A list of clans can be found by going into the Clan Halls in any Outpost.
