Horizons was a dark ride attraction at Epcot (then known as EPCOT Center), a theme park at Walt Disney World in Bay Lake, Florida. Located on the eastern side of the "Future World" section of Epcot, the attraction used Disney's Omnimover system, which took guests past show scenes depicting visions of the future. It is believed to be the sequel to Walt Disney's Carousel of Progress, an attraction in Tomorrowland at Walt Disney World's Magic Kingdom. Horizons was the only attraction in "Future World" to showcase all of Epcot's "Future World" elements: communication, energy, transportation, anatomy, along with humankind's relationship to the sea, and the land. The attraction officially opened on October 1, 1983, as part of Phase II of Epcot. Horizons originally closed in December 25, 1994, a little more than a year after General Electric had ended its sponsorship of the attraction. Horizons re-opened on December 24, 1995 due to the closure of two other attractions that were down for refurbishment in "Future World", Universe of Energy and World of Motion.

The attraction, although extinct, still retains a sizable cult following, especially among Disney park aficionados.

The name was changed to Futureprobe to help appeal the attraction toward international guests who wouldn't understand or appreciate Century 3. In the end, the Futureprobe name was scrapped due to the medical connotation of the word "probe". After much debate, GE and Disney officials settled on the name Horizons. Prior to the start of construction, the project's budget was slashed by $10 million (USD). The building size was reduced and the length of the ride was shrunk by 35%, shortening the ride length by . Horizons opened exactly one year after Epcot opened and was located between World of Motion and the Universe of Energy. The Wonders of Life pavilion became Horizons' new neighbor in 1989, and World of Motion closed in 1996. Horizons remained operational until World of Motion's successor, Test Track, was ready to open to the public in early 1999. It was proposed that Horizons would be the sequel to the
