OGLE-2007-BLG-349L: Located 8,000 light years from Earth, this circumbinary system is the latest confirmed such star system to date. The exoplanet is a Jovian world orbiting its two stars at nearly the distance as Jupiter is from our Sun.
Tatooine’s galore: Other already-confirmed circumbinary systems include Methuselah (the M4 system), Kepler 16, 34, 35, 1647, and HD 98800. A good list of 10 such systems can be found here: http://www.ua-magazine.com/tatooine-anyone/
*bonus* HD 133131: Not exactly a circumbinary system, but it’s a double-star system (wide; the stars orbit each other every 4,000+ years) where each star has at least one planet orbiting it.
