This depends on whether you count Pluto as a planet or not. If you don't, then Neptune has the longest orbit period (nearly 165 Earth years). If you do, then Pluto has a orbit period of 248.1 years.
If you count Pluto, you might also count Sedna which takes 12,050 years. Sedna is 2/3 the size of Pluto and it's 960 times as far from the Sun as the Earth.
