What are the three largest stars in our galaxy?

My best list of the largest stars by radius is:

Mu Cephi            about 1500 times the Sun
Betelgeuse          about  900 times the Sun
Antares             about  530 times the Sun
Deneb           about  145 times the Sun


The largest stars by mass, which probably exceed 50 - 100 times the Sun's mass are:

Cygnus OB2 Star number 12
Eta Carina
Zeta Scorpii
HD 93129A
P Cygni
