Varies from model to model, but on my 15" Retina MBP, it's tucked in under the left speaker grille, near the Tab key. Pull up some software that shows you a live mic level (e.g. System Preferences -> Sound -> Input tab), and rub your finger gently over the grille, and you can usually tell roughly where it is by the spike in input volume.

If you're wondering about blocking it off, though, that's much harder than the camera. You'd basically have to open the laptop and unsolder the mic capsule -- or mount a little white noise generator right over the mic, but then you can't close your laptop. :-)
