There were two, Jupiter and Saturn.
The most well-known probe to explore Jupiter is the Juno spacecraft, which has been studying the planet since 2016. Other past probes that have collected data on Jupiter include Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, and Galileo.
Voyager 2, which flew by the giant planet in 1989.
The answer is Voyager 2. It reached Uranus in 1986.

Four spacecraft have been sent to Saturn: Pioneer 11, Voyager 1, Voyager 2, and the Cassini-Huygens mission. Voyager 1 and Voyager 2 made flybys of Saturn while the Cassini-Huygens mission orbited the planet for over 13 years, studying its moons and rings in detail.
The spacecraft Voyager 1 conducted a successful flyby of Saturn in 1979. It captured close-up images of Saturn's rings, moons, and atmosphere during its brief encounter with the planet. Voyager 1 continued its journey out of the solar system and is now in interstellar space.

Voyager 2 is the only spacecraft to currently visit Neptune, passing 3,000 miles from the planet on August 25, 1989.
No human has visited Jupiter. However, the spacecraft missions Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, Galileo, Cassini, and Juno have all conducted flybys or orbited Jupiter to gather data and study the planet.

Voyager 2 flew by Neptune in 1989, coming within 30,000km of the planet.
No human has been on the planet Uranus. The only spacecraft was Voyager 2 which went by Uranus on January 24th 1986.
