Well, since the universe is so big, there are billions of planets we don't know anything about, but the largest planet in our solar system is Jupiter.

No one knows teh largest planet in the universe. We're still discovering other planets orbiting other suns. The only planets we've found are about or bigger than Jupiter. We probably will never know this answer. The biggest planet in OUR solar system however is Jupiter.

You can have a planet up to the size of 15 times the mass of Jupiter. Any bigger than that and you have a Brown Dwarf ( a star that didn't actually start "burning" hydrogen.)
So the largest planet could be that massive, but they would actually be about the same radius of Jupiter. Since the pressure and temperatures involved actually balance at about the size of Jupiter.

If you turn the other direction from the Morning Star (not to Never-Never Land) and go straight on for several hours (or more depending on your speed) you will find a gaseous planet much like Jupiter but much much bigger. It will be so big that if it were any bigger fusion would start in the middle and it would become a star. That is the biggest planet in the universe. Not having a good map of the area, I can't show you where it is. The biggest planet around here is Jupiter.

HAT-P-1 b is the largest KNOWN.
With a radius about 1.38 times Jupiter's, HAT-P-1 b is the largest planet known. In spite of its large size, its mass is only half that of Jupiter.

Well... considering that we are far from discovering all the planets in the Universe, I don't think anyone can name it.

according to the site, the smallest "star" discovered so far (march 2005) is only 16% bigger than Jupiter, which makes the biggest possible planet only 15.9% bigger than Jupiter.

We are not sure right now because the Universe is such big

not known for sure because there are millions of undiscovered planets
