Former Apprentice and Celebrity Big Brother star Katie will be joined by celebrities and guests on the new show, where she will debate a proposed rule on everyday life including topics on weight, sex and benefits.
The audience will then have to decide if Katie's motion is thrown out.
Speaking in her column in The Sun, Katie said: "You have the pleasure of seven weeks of me on TV exploring what would happen if I ruled the world. I'll be hitting the streets to test out my rules for life and seeing how my lovely audience react to Hopkins' cunning plans.
"Stand by your beds, this one is going to get messy."
TLC chief Clare Laycock said: "The show is a unique forum to thrash out the issues being ranted about in pubs, on Twitter and in living rooms across Britain."
It was rumoured in April that controversial TV personality Katie was being lined up for a primetime show following the success of her weight-loss documentary My Fat Story.
If Katie Hopkins Ruled the World starts this summer on TLC.
