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.
The brightest star as seen from Earth is the sun. The brightest star in the night sky is Sirius.
The brightest star in the sky is Sirius. The brightest object that looks like a star is the planet Venus - which is brighter than any star. You can see it these days (Aug. 2010) after sunset in the west, as a very bright star.
The main star of Virgo is Spica, is the brightest star in the constellation Virgo, and the 15th brightest star in the nighttime sky. It is 260 light years distant from Earth.

Alcyone, with an apparent magnitude of 2.86
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.
Our sun is not the brightest star in the universe. It only appears brighter because it is much close than any other star. The brightest star as it appears in the sky is Sirius.

The sun is the brightest star as seen from Earth, but that is only because it is much closer to us than any other star.
That question cannot be answered. We would have to know the magnitude of every star in the universe. The universe is infinite (and expanding). It's impossible to answer your question.
The brightest star in the constellation Lyra is Vega. It is one of the most prominent stars in the summer sky and is located relatively close to our Solar System. Vega is known for its bluish-white color and its importance in navigation and astronomy.
