That would be Uranus. Uranus has a diameter of about 51,000km, making it the third largest planet in terms of radus/diameter/volume etc. but it's mass is only 15 times that of Earth, less than Neptune, making it the fourth largest in terms of mass.
Uranus is the 3rd to largest planet.
The largest planet in our solar system is Jupiter with an approximate radius of 70,000 km (smaller in the polar direction, larger in equatorial due to its spin). The largest planet known might be the exoplanet (outside the solar system) called TrES-4 and thought to be about 1.7 times the size of Jupiter - but ithe definition for it and even potentially larger planetary candidates is still a subject of debate since it fits the characteristics of a brown dwarf (a type of small star) and the distinction begins to blur somewhat as a planet's size becomes large enough.
Saturn has a radius of 36,184 miles (58,232 kilometers). This makes Saturn the second largest planet in the Solar System, after Jupiter.
No. Kepler-22b is between the sizes of Earth and Neptune. The largest known planet is HAT-P-32b which gas about twice the radius of Jupiter.
Saturn's equatorial circumference is 235,298 miles, or 378,675 kilometers. Saturn's equatorial radius is 60,268 kilometers. It is the second largest planet in the Solar System.
Uranus is the 3rd to largest planet.
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
Jupiter is the largest planet and therefore has the largest radius. The radius of Jupiter is 43,441 miles (69,911 kilometers).

Within our solar system. Eris a dwarf planet with a radius of about 1,300 km.
Jupiter is that planet.
Saturn has a radius of 36,184 miles (58,232 kilometers). This makes Saturn the second largest planet in the Solar System, after Jupiter.
Jupiter is the largest planet, with an equator radius of ~71,492km and polar radius of ~66,854km. Jupiter also has a huge mass, which is 2.5 times that of all the other planets in our solar system put together!
Jupiter is the largest planet in the solar system with a 71,492 mile equatorial radius (11.209 times larger than the earth).
Jupiter has the largest diameter (the radius is half the diameter, of course).
Uranus if you're going by mass, Neptune if you're going by radius/volume.
Ganymede, the largest moon in the solar system, has a radius of 2,634.1 km and orbits Jupiter, the fifth planet from the sun in our solar system.
