Lego will no longer partner with Shell, due to controversy over drilling in the arctic.
The group Greenpeace made a video criticizing the partnership, showing Lego pieces covered in an oil spill. The video quickly went viral.
Lego has used the Shell logo on some of its pieces since the 1960s.
Neither company is commenting on the split.
Earlier this year, Lego officially became the biggest toy maker in the world, based on revenue and profit.
