There were two, Jupiter and Saturn.
Voyager 2, which flew by the giant planet in 1989.
Voyager 1
Jupiter is Gaseous Planet so no Lander/Rover can land on Jupiter. Voyager is basically a Spacecraft and spacecraft is used as flyby around a planet or object. It had a flyby of Jupiter in 1979. It is now outside the heliopause - the "bubble" of plasma coming from the sun otherwise known as solar wind. It is now out in what we consider interstellar space and still transmitting.
Only one through 2009. The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton and discovered 5 new inner moons.
Well, Voyager is now well beyond much useful gravitational influence of any of the solar system's planets. What we have learned is that planetary gravity wells can be used to provide a boost to passing spacecraft. Since Voyager most spacecraft to the outer planets spend some time in the inner system first, performing slingshots from one planet to the next to increase velocity. Each of these maneuvers robs a wee bit of the planet's angular momentum.

Voyager 2
voyager 2
Voyager 2 is the only spacecraft to currently visit Neptune, passing 3,000 miles from the planet on August 25, 1989.
Pioneer
Voyager 2, which flew by the giant planet in 1989.
Voyager 2 flew by Neptune in 1989, coming within 30,000km of the planet.
Voyager 1
No human has been on the planet Uranus. The only spacecraft was Voyager 2 which went by Uranus on January 24th 1986.
NO. during the summer of 1989, NASA's Voyager 2 was the first spacecraft to see the planet Neptune.
Voyager 2 was launched first. It's trajectory was designed to take advantage of an unusually convenient alignment of the planets allowing the inclusion of Uranus and Neptune fly bys in the probe's mission. Voyager 1 was launched after its sister probe, but on a faster trajectory which enabled it to reach Jupiter and Saturn sooner at the expense of visiting the outer planets.
