The most massive star (The star with the most mass) is a star in a super star cluster called R136 or RMC 136 in the Large Magellanic Cloud (LMC). [See related link for more information]
The star, for all its fame has a rather unremarkable name of R136a1. It has the mass of about 265 -> 300 solar masses (256 x the mass of the Sun - See related question).
See related link [BBC] for a pictorial size comparison.
It is a blue supergiant with a spectral type of O3. Because of its mass and intense luminosity (10 million times that of our own Sun) it, astronomically, will have a very short lifetime in the millions of years rather than billions.
At the end of its life, R136a1 will explode as a supernova and because of its relatively close distance to Earth (165,000 light years/ALU [See related question] it might be visible during the day.
This question is about the most massive star (mass), not the largest (Radius) [See related question]

They are slow burning stars, with just enough mass to be on the main sequence.
Browns dwarfs are sometimes thought to be on the main sequence, but they do not have enough mass to initiate hydrogen fusion.

∙ 12y agoThe most massive MAIN SEQUENCE stars would be the 00 (Oh Zero) type star, and are thought to have a mass about 100x that of the sun. These are also the biggest and brightest main sequence stars, perhaps as big as 200-300 times the radius of the sun, and over a million times brighter. Because they are so big, these stars use up their fuel much faster than less massive stars, and therefore remain on the main sequence for only a few million years.
Previous answer (Absolutely WRONG, Hypergiants are NOT Main Sequence stars):
Hypergiants.

∙ 13y agoOver a period of time, Blue supergiants are the most massive.
However:
When some stars come off of the main sequence, they form into red supergiants, and over a period of time, due to pressure they can suddenly find an extra bit of fuel in other elements and reenter the main sequence phase. They do contact from the red supergiant phase back into a blue supergiant but not for very long, thousands of years rather than millions.

∙ 11y agoThe largest estimated mass for a star is 265 times the mass of our Sun, the star being R136a1, located in a cluster of the Large Magellanic Cloud, a satellite galaxy of the Milky Way. There are larger stars in radius, and the masses of some cannot be accurately determined, falling in a range of 25 to 100 solar masses. The upper limit for existing stars was thought to be between 100 and 150 solar masses.

∙ 10y agoOur Sun, Proxima Centauri, Barnard's Star (as well as any other red dwarf), Beta Pictoris, Gamma Virginis, ... You can find some more in the Wikipedia article on "main sequence". Or just look up some sample stars in the Wikipedia or similar sources; if the star is a main sequence star, it will usually say so. Note that many of the well-known stars (the brighter stars) are NOT main-sequence stars; the brighter stars are often giant stars that have left the main sequence. This basically means that they have run out of hydrogen.

Size of main sequence star?
A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
Main sequence stars are also called stars?
A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into helium. It is then usually called a dwarf star. This is the longest period in a stars lifetime. Our Sun is a yellow dwarf in "main sequence".
What are some star types which are not main sequence stars?
Some examples of star types that are not part of the Main Sequence are:Red Giants, Blue Giants, Brown Dwarfs, and White Dwarfs.When stars are plotted on a chart that compares their Temperature (color) to their Brightness (Luminosity), most of them fall into a diagonal line across the chart.That chart is known as a Hertzsprung-Russell diagram and the diagonal line on it is called the Main Sequence of stars.Stars on the Main Sequence fit this pattern because they are in balance between collapse and expansion. Their gravity that is trying to collapse them is in balance with their nuclear fusion that is trying to expand them.A difference to notice between Main Sequence stars and other stars is:Main Sequence stars are dimmer if they are cooler and brighter if they are hotter.Giant stars are brighter whether they are hot or cool.Dwarf stars are dimmer whether they are hot or cool.
How can you explain the Algol paradox?
In some binary systems, the less-massive star has become a giant, while the more-massive star is still on the main sequence. If higher-mass stars evolve faster than lower-mass stars, how do the lower-mass stars in such binaries manage to leave the main sequence first? This is called the Algol paradox, after the binary system Algol.
Does smaller mass stars have a greater luminosity than larger mass stars?
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.

Are main sequence stars only the Right type of stars?
By definition and experiance sol as a main sequence star and as a class planet earth and the earths moon with some comets as life as we know it. But a star like a gas giant its gravity may be to strong. Sol as a main sequence stars has the right gravity for earth and counter clock wise rotation and gravity

What are the different of the stars?
Stars are classified by their type and temperature. Amongst some of the types of stars in our galaxy are white dwarfs, blue giants, and red supergiants. Our own Sun is a yellow dwarf, and like most stars is a main-sequence star.
What are some of the elements found in stars?
All of them - but mostly hydrogen & helium.
Why is it that there are main sequence stars which are hot and others are cool and dim?
some stars are hotter than others because they have more hydrogen to use and create heat with. BTW- answered by a 6th grader.

What is sequence stars?
Information on millions of stars shows that there is a relationship between temperature and brightness. Surface temperature is measured in degrees C and brightness is measured in absolute magnitude (the star's brightness at a standard distance). If all the stars are plotted on a graph of temperature against absolute magnitude, called a Hertzsprung-Russell diagram, very many of them lie close to a straight line that is called the Main Sequence. There are some stars that do not lie on the Main Sequence, notably the red giants that are very bright despite having a relatively low temperature. The Sun is right in the middle of the Main Sequence showing it is an average star in the middle of its life and very stable.
