"It's a Small World" is the pilot episode from the iconic American television series Leave It to Beaver (1957–1963). The pilot (originally proposed as Wally and The Beaver) was first televised April 23, 1957 on the syndicated anthology series, Studio 57, without a laugh track nor the series' well known theme song, "The Toy Parade". It never aired as an episode within the series. It was televised again in October 2007 as part of TV Land's 50th anniversary celebration of Leave It to Beaver. It was released to DVD in 2005. The series made its CBS debut several months later on October 4, 1957 with the episode, "Beaver Gets 'Spelled".

Wally and Beaver want a new bicycle. Frankie Bennett, a mischievous boy, tells them new bikes can be had at a local dairy in exchange for 1,000 bottle caps from the company's products. The boys collect the bottle caps, but, in attempting to redeem them, learn they've been duped. Ward takes pity on the boys and buys them a bicycle.

"It's a Small World" was filmed with a single camera, in full screen black-and-white at Republic Studios and the Universal Studios backlot. With some modifications, the façade of the Cleaver house in the pilot became that of the Cleaver house in the first two seasons of the series. Some decorative elements (like the curtains in the boys' bedroom) would be retained for the series. Joe Connelly and Bob Mosher wrote the teleplay with Jerry Hopper directing the episode. Richard Lewis produced the episode.
