Tonight, Jupiter, fifth planet from the Sun and largest planet in the solar system will be setting four hours after the Sun. To see Jupiter this evening, go out just after the sky starts to dim in the evening and look West-Southwest. If it is clear, you will see a bright yellow 'star' that, is in fact, the planet. Oh, yes, Venus is nearby, too, which means that Jupiter is the second brightest star.
To aid in one's planet hunting, a pair of binoculars is a good idea as, while the planets are rather bright, you will be fighting the brightening sky, which can make finding them difficult.
