Six out of 10 of you have been bullied, according to a survey carried out for Newsround.
It's the same figure for both boys and girls, but the biggest bullying problem is amongst eight to 12-year-olds.
A third of you said that your school helped deal with the problem, either by speaking to the bully or speaking to the bully's parents.
The survey spoke to 1,000 children across the UK, aged between eight and 15 during the summer holidays.
It seems the biggest problem is in the West Midlands, where 80% of you said you'd been bullied either physically or verbally.
