As the question specifies brightness, the brightest star in the Universe is our Sun - because it is the closest star to us.

The most luminous star is another question: See related question.

What is the largest know star in the universe?

From Earth the Sun is obviously the brightest star. Otherwise Sirius (The Dog Star) is brightest star discovered so far with a magnitude of -1.42. One of the most luminous stars in the Galaxy is called The Pistol Star (but dust hides it from view) Yes, from Earth the Sun is the brightest star. But that's not the question: the brightest star in the universe is certainly not the Sun, nor is it Sirius; Spica for instance, is over 10 times the mass of the Sun, thus having a far greater luminosity. But the light years separating Spica from Earth reduces it to the 15th brightest star in the nighttime sky. And the Pistol Star is only one of the brightest stars in the Milky Way Galaxy... The universe however, houses many stars superior to the Pistol Star. The problem with the question is it refers to such an astronomical entity, the vast universe. And as such, it may never be able to be answered with complete accuracy... That isn't the question either, the brightest star known in the universe is R136a1, a blue hyper-giant which is not only the most massive star known, at 265 solar masses, but the brightest. It shines at 8,700,000 times the luminosity of the sun and is a member of the R136, a super star cluster around the centre of the tarantula nebula in the the magellanic cloud, a satellite galaxy of the Milky way.
