On 12 January, 2010 a huge earthquake hit Haiti, destroying most of the Haitian capital Port au Prince.
The tremors were so powerful they killed around 220,000 people and around 1.5 million people were left homeless.
Two years on, gradually parts of the island are being rebuilt, thanks to the efforts of organisations like children's charity SOS Children - but life is still very hard.
The recovery effort is mainly funded by billions of pounds of aid that's been donated by people all over the world.
