Almost 130,000 children will be homeless at Christmas this year, according to a homeless charity.
Shelter said 127,992 kids will be without a home on Christmas Day, and 83,962 of those will be in London.
The charity has launched a campaign to try raise awareness of the problem, and encourage the government to act.
Shelter is also unhappy that more than one million children are living in housing that is unhealthy, temporary or far too crowded.
As part of the campaign the charity is going around the country to highlight how many homeless kids there are.
On Friday Shelter lit 83,962 candles in London's Trafalgar Square.
The director of Shelter, Adam Sampson, said: "It's shocking that, in the 21st century, there are thousands of children in Britain waking up homeless on Christmas Day.
"Living in temporary accommodation robs children of security, health and a fair chance in life."
