Mattel says nearly 50,000 toy cars made in China were decorated with paint containing lead, which can be harmful.
It is also recalling 1.9m magnetic toys including Batman, Barbie and Polly Pocket as the magnets may come loose.
There are worries they could be harmful after three kids in America had surgery after swallowing more than one magnet.
Toy expert Gary Grant told Newsround to check with your parents if you're worried your toys are among those affected by the recall.
He said: "It's important to remember that it's not all of the Polly Pocket, Barbie and Batman ranges that are affected, it's limited toys only.
"Safety is the most important part of toys and the recall is happening because safety checks have highlighted a possible problem."
It is the second time in two weeks that the American toy-maker has had to recall some of its products.
Then, Mattel pulled 94,000 Fisher-Price toys off shop shelves in the UK and Ireland over concerns about levels of lead in their paint.
Lots of you have been emailing Newsround about this story and some of you are worried you're going to end up with no toys, but Gary said you're unlikely to lose out if you contact Mattel directly.
