Lots of children's charities are teaming up to try and get more done to help kids who run away from home.
It's thought as many 140,000 people younger than 18 run away from home every year in the UK.
Paul Tuohy, who is the boss of a charity called Missing People, said: "Children can run away for all sorts of problems, like bullying for example."
Mr Tuohy added that there is a real need for some sort of plan across the country to help runaway children.
The charities want:
- Safe places for runaways to go to so they aren't sleeping on the streets
- Safe people for them to be able to talk to about their problems
- Clear rules that are the same across the UK on how to deal with runaways
Mr Tuohy says at the moment the problem of missing people isn't seen as important enough by some people.
The charities want politicians to sign a giant petition in the shape of a trainer to represent all the children who run away from home.
