Weebles is a range of children's roly-poly toys that originated in 1971 by the US toy company Playskool. They are egg-shaped, so tipping one causes a weight located at the bottom-center to be raised. Once released, the Weeble is restored by gravity to an upright position. Weebles have been designed with a variety of shapes, including some designed to look like people or animals.

The catchphrase "Weebles wobble, but they don't fall down" was used in advertising during their rise in popularity in the 1970s and during successive relaunches in the early 2000s. The line was coined by advertising executive Walter Cohen at Benton & Bowles when he and his partner Bernard Most were assigned to the account in 1971. The pair (as the creative team Bernie & Walter) used the phrase when they created the first TV commercials for the new product.

The Weebles 1971–2011 Price Guide and Index lists and shows every Weeble model made over the preceding 40 years. There are 116 Weebles in total (83 regular; 21 peelable; 12 tumbling) including all egg-shaped sizes and variations made during 1971–1983. In 2011, Hasbro started making a new line of larger egg-shaped Weebles and had produced 42 new Weebles as of July 2011.

A wide range of accessories was available for the Weebles, including vehicles, buildings and furniture. Some sets had themes, such as the Weebles circus set.

In the United Kingdom, Weebles were manufactured and marketed by Airfix under licence from 1973 onwards.
