There is no definite answer to this question. We've found planets bigger than Jupiter.
There are a 100 billion planets in our galaxy alone and we've found more than a thousand of them since finding planets is a very difficult job. Astronomers have found planets more massive than Jupiter, which was once supposed to be the biggest planet. The answer could be a brown dwarf (neither a planet or a star)
