I know low blood pressure can cause fainting, but can high blood pressure do it too?

In brief: Rarely
If blood pressure is really high, it could cause a stroke (very serious) and some strokes can cause abrupt loss of consciousness (fainting); generally, low blood pressure is a much more common cause of loss of consciousness (not enough blood flow to the brain).
