"It's a Small World" (stylized in all lowercase) is a water-based boat ride located in the Fantasyland area at various Disney theme parks worldwide, including Disneyland Park in Anaheim, California; Magic Kingdom at Walt Disney World Resort in Bay Lake, Florida; Tokyo Disneyland, Disneyland Paris; and Hong Kong Disneyland, with its inaugural version having premiered at the 1964 New York World's Fair before permanently moving to Disneyland.

The ride features over 300 audio-animatronic dolls in traditional costumes from cultures around the world, frolicking in a spirit of international unity, and singing the attraction's title song, which has a theme of global peace. According to Time.com, the Sherman Brothers' song "It's A Small World" is the most publicly performed song of all time. In recent years, the Small World attractions at the various Disney parks have been updated to include depictions of Disney characters, albeit in a design compatible with the original 1960s design of Mary Blair, alongside the original characters. Countries in the Disneyland version include: The North Pole, Norway, Canada, Sweden, Denmark, England, Wales, France, Spain, Scotland, Ireland, The Netherlands, Belgium, Italy, Switzerland, Germany, Russia, Greece, Israel, Saudi Arabia, Pakistan, Afghanistan, India, Indonesia, Thailand, China, North Korea, South Korea, Japan, Egypt, Uganda, Kenya, Chile, Argentina, Peru, Ecuador, Colombia, Venezuela, Brazil, Mexico, New Zealand, Philippines, Hawaii (United States), Australia, Tahiti, Papua New Guinea, and the United States.
