The Teenie Beanies are miniature Beanie Babies that were offered in McDonald's promotions between 1997 and 2000, in 2004, and in July 2009.

The Teenie Beanies were most in demand from McDonald's in the first year they were offered, and declined in popularity every year thereafter, even though more were produced each time.

During the height of their popularity, which was in 1998, Teenie Beanies were the cause of a lot of fights at various McDonald's locations, resulting in calls to police, criminal charges, and injuries. . These included a Miami area McDonalds employee, who was charged with the theft of the toys . Though they were sold for around $2 each along with a Happy Meal, they were often resold in 1997 and 1998 for much higher prices on the secondary market after the promotion.

Some McDonalds locations exhausted their supplies of Teenie Beanies before the promotion was over.

Teenie Beanie Babies returned to McDonalds in July 2009, featuring Beanie Babies 2.0, the subseries of Ty Beanie Babies. Consumers could log onto http://www.ty.com/ and play online with their new Teenie Beanie as a marketing decision to raise public awareness and garner interest in the Beanie Babies 2.0 virtual pets. Originally, there was a 30-day trial period for playing with the toys online, but now the company has decided to allow consumers to keep their virtual pets for an undisclosed period of time (albeit indefinite.)
