In our solar system ... the group of planets associated with our Sun ... the biggest one
is Jupiter.
Outside of our solar system, literally hundreds of planets have now been been identified,
many of them more massive and most likely bigger than Jupiter.
Jupiter is the largest planet in our Solar System
As of 2007:
XO-3b The planet has a radius of 1.92 times Jupiter, the largest of any known extra-solar planets.
TrES-4 Has the largest diameter but is very rarefied so weighs very little.
Jupiter. Some say that the Sun makes up 99.9% of the mass in our solar system and Jupiter is another 0.05%. That means the remaining 0.05%, which is everything else, is only as massive as Jupiter when it's all combined.
If you mean it on solar system it is Jupiter. :)
I think largest planet known in whole universe is 11 Ursae Minoris b .

Pluto used to be a planet.
